Exhibit 10.1

IPG PHOTONICS CORPORATION
2008 EMPLOYEE STOCK PURCHASE PLAN
(As Amended and Restated Effective December 1, 2018)

ARTICLE I
INTRODUCTION

1.01 Purpose. IPG Photonics Corporation (the "Company") established and
maintains this IPG Photonics Corporation 2008 Employee Stock Purchase Plan, as
amended from time to time (the "Plan") to provide employees of IPG Photonics
with an opportunity to purchase Common Stock of the Company through accumulated
payroll deductions. The Company has amended and restated the Plan effective
December 1, 2018 (the "Restatement Date," and the Plan on and after the
Restatement Date, the "Restated Plan").

1.02 Operation. It is the intention of the Company to have the Plan qualify as
an "employee stock purchase plan" under Code Section 423. Accordingly, the
provisions of the Plan will be administered, interpreted and construed so as to
extend and limit Plan participation in a manner consistent with the requirements
of Code Section 423. However, the Company makes no undertaking or representation
to maintain such qualification. In addition, the Plan authorizes the purchase of
shares of Common Stock under a Non-Code Section 423(b) Component, pursuant to
rules, procedures or sub- plans adopted by the Board and designed to achieve
tax, securities law or other objective, provided, however, that U.S. Employees
will not be permitted to purchase shares of Common Stock under the Non- Code
Section 423(b) Component.

ARTICLE II
DEFINITIONS

2.01 "Administrator" means the Compensation Committee of the Board or any
committee designated by the Board to administer the Plan pursuant to Article
VII.

2.02 "Affiliate" means any entity, other than a Subsidiary, in which the Company
has an equity or other ownership interest.

2.03 "Board" means the Board of Directors of the Company.

2.04 "Change in Control" means the occurrence of any of the following events:

Company, (ii) any wholly- owned subsidiary of the Company, or (iii) any employee
benefit plan (or related trust) sponsored or maintained by the Company or any
Affiliate, becomes a "beneficial owner" (as defined in Rule 13d-3 under the
Exchange Act), directly or indirectly, of securities of the Company having fifty
percent (50%) or more of the combined voting power of the then-outstanding
securities of the Company that may be cast for the election of directors of the
Company (other than as a result of an issuance of securities initiated by the
Company in the ordinary course of business) (the "Company Voting Securities");
provided, however, that the event described in this paragraph (a) shall not be
deemed to be a Change in Control by virtue of any underwriter temporarily
holding securities pursuant to an offering of such securities;

(b) During any period of two consecutive years, individuals who at the beginning
of any such period constitute the Board (the "Incumbent Directors") cease for
any reason to

1

--------------------------------------------------------------------------------

constitute at least a majority of the Board, unless the election, or the
nomination for election by the stockholders of the Company, of each new director
of the Company during such period was approved by a vote of at least two-thirds
of the Incumbent Directors then still in office;

(c) As the result of, or in connection with, any cash tender or exchange offer,

election of directors of the Company immediately prior to such transaction; or

solely because any person acquires beneficial ownership of more than fifty
percent (50%) of the Company Voting Securities as a result of the acquisition of
Company Voting Securities by the Company that reduces the number of Company
Voting Securities outstanding; provided, however, that if after such acquisition
by the Company such person becomes the beneficial owner of additional Company

the case of the Participant's death, to the Participant's designated
beneficiary. If no beneficiary is designated or if a beneficiary designation is
not permitted by the Administrator, the amounts credited to the Participant's
account shall be paid to the Participant's spouse, if any, and if none, to the
Participant's estate.

ARTICLE V
OPTION GRANTS AND EXERCISE

5.01 Grant of Option. On an Enrollment Date of each Offering Period, each
Participant shall be deemed to have been granted an option to purchase on the
Exercise Date of the Offering Period a number of shares of Common Stock
determined by dividing the Participant's accumulated payroll
deductions/contributions as of the Exercise Date by the Purchase Price.

the lower of (a) eighty-five percent (85%) of the Fair Market Value of a share
of Common Stock on the Enrollment Date or (b) eighty-five percent (85%) of the
Fair Market Value of a share of Common Stock on the Exercise Date; provided,
however, that the Purchase Price may be adjusted by the Administrator pursuant
to Article VIII.

5.03 Limitation. Except as provided below or otherwise provided by the
Administrator, the maximum number of shares of Common Stock that a Participant
may purchase with respect to any Offering Period is the number of shares
determined by dividing $12,500 by the Fair Market Value of a share of Common
Stock on the Enrollment Date. Notwithstanding the preceding sentence, the
maximum number of shares of Common Stock that a Participant may purchase with
respect to the First Offering

5

--------------------------------------------------------------------------------

Period shall be the number of shares determined by dividing $25,000 by the Fair
Market Value of a share of Common Stock on the Enrollment Date for First
Offering Period.

5.04 Option Exercise. Except as provided in Section 4.07, a Participant's option
for the purchase of shares of Common Stock will be exercised automatically on
the Exercise Date, and the maximum number of full shares subject to an option
will be purchased for such Participant at the applicable Purchase Price with the
accumulated payroll deductions/contributions in the Participant's account.
During a Participant's lifetime, the Participant's option to purchase shares
hereunder is exercisable only by him or her.

5.05 Fractional Shares. No fractional shares of Common Stock will be purchased;
any payroll deductions/contributions accumulated in a Participant's account that
are not sufficient to purchase a full share of Common Stock will be retained in
the Participant's account for the subsequent Offering Period.

5.06 Purchase Reductions. Notwithstanding anything herein to the contrary, the
Administrator shall have the discretion to reduce the number of shares of Common
Stock to be purchased by Participants with respect to an Offering Period and to
allocate such reduced number of shares among Participants in such Offering
Period, so long as such reduction and allocation is done in a manner consistent
with Code Section 423. Any payroll deductions not applied to the purchase of
shares of Common Stock shall be promptly refunded to Participants after the
Exercise Date of the Offering Period to which such reduction applies.

5.07 Delivery. After each Exercise Date on which a purchase of shares of Common
Stock occurs, shares purchased upon exercise of the Participant's option shall
be held in such Participant's account. As soon as administratively practicable
after the Participant's request, the Company will distribute to such
Participant, as appropriate, the shares in each Participant's account in a form
determined by the Administrator (in its sole discretion) and pursuant to rules
established by the Administrator. No Participant will have any voting, dividend,
or other stockholder rights with respect to shares of Common Stock subject to
any option granted under the Plan until such shares have been purchased and
delivered to the Participant's account.

ARTICLE VI
COMMON STOCK

6.01 Available Shares. Subject to Section 9.05, the maximum number of shares of
Common Stock that will be made available for sale under the Restated Plan will
be 400,000 shares of Common Stock, plus an annual increase, if any, to be added
on the first day of each Fiscal Year so that the total number of shares of
Common Stock available shall be equal to the greater of (i) the number of shares
of Common Stock available under the Plan as of the last day of the immediately
preceding Fiscal Year and
(ii) the lesser of (A) 400,000 shares of Common Stock and (B) seventy-five
hundredths of one percent (0.75%) of the outstanding shares of Common Stock on
the last day of the immediately preceding Fiscal Year. Any or all shares of
Common Stock may be granted under the Code Section 423(b) Component.

6.02 Registration. Shares of Common Stock purchased by a Participant under the
Plan will be registered in the name of the Participant or, to the extent
required or if the Participant so directs by written notice to the Administrator
prior to the Exercise Date, in the name of the Participant and his or her
spouse.

7.01 Administration. The Administrator shall administer the Plan. The
Administrator will have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility, to
adjudicate all disputed claims filed under the Plan and to establish such

--------------------------------------------------------------------------------

procedures that it deems necessary for administration of the Plan (including,
without limitation, to adopt such rules, procedures and sub-plans as are
necessary or appropriate to accommodate the specific requirements of applicable

determination made by the Administrator shall, to the fullest extent permitted
by law, be final and binding upon all parties.

aggregate number of shares of Common Stock that may be issued under the Plan
(except pursuant to Section 9.05), or (b) the class of Employees eligible to
receive options under the Plan, other than to designate Participating Companies;
and provided, further, that, subject to Section 8.02, no termination,
modification, or amendment of the Plan may, without the consent of an Employee

adversely affect the rights of such Employee under such option. In addition, and

necessary under Code Section 423 (or any successor rule or provision or any
applicable law or regulation), the Company shall obtain stockholder approval in
such a manner and to such a degree as required.

8.02 Administrator Authority. Without stockholder consent, the Administrator
shall be entitled to change the Offering Periods, limit the frequency and/or
number of changes in the amount withheld during an Offering Period, establish
the exchange ratio applicable to amounts withheld in a currency other than U.S.
dollars, permit payroll withholding in excess of the amount designated by a
Participant in order to adjust for delays or mistakes in the Company's
processing of properly completed withholding elections, establish reasonable
waiting and adjustment periods and/or accounting and crediting procedures to
ensure that amounts applied toward the purchase of Common Stock for each
Participant properly correspond with amounts withheld from the Participant's
Compensation or otherwise contributed by the Participant, and establish such
other limitations or procedures as the Administrator determines in its sole
discretion advisable that are consistent with the Plan, in each case so long as
any such action is consistent with Code Section 423. None of the foregoing
actions shall be considered to have adversely affected any right of any
Participant.

8.03 Accounting Treatment. In the event the Administrator determines that the
ongoing operation of the Plan may result in unfavorable financial accounting

(a) altering the Purchase Price for any Offering Period including an Offering
Period underway at the time of the change in Purchase Price;

purchase during any Offering Period; and

Section 5.06.

None of the foregoing actions shall require stockholder approval or shall be
considered to have adversely affected any right of any Participant.

ARTICLE IX
MISCELLANEOUS

9.01 Transferability. Neither payroll deductions/contributions credited to a
Participant's account nor any option or other rights with regard to the exercise
of an option to receive shares of Common Stock under the Plan may be assigned,
transferred, pledged or otherwise disposed of in any way by the Participant
other than by will, the laws of descent and distribution, or as provided in
Section 9.04.

9.02 Use of Funds. The Company may use all payroll deductions/contributions
received or held by the Company under the Plan for any corporate purpose, and
the Company will not be obligated to segregate such payroll
deductions/contributions, unless otherwise required by applicable local law.

appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company), a Participant will only have the rights of an unsecured
creditor with respect to such shares.

9.03 Reports. Individual accounts will be maintained for each Participant.
Statements of account will be given to Participants at least annually, which
statements will set forth the amounts of payroll deductions/contributions, the
Purchase Price, the number of shares of Common Stock purchased and the remaining

9.04 Designation of Beneficiary.

(a) If permitted by the Administrator in its sole discretion, a Participant may
designate a beneficiary who is to receive any shares of Common Stock and cash,
if any, from the Participant's account under the Plan in the event of such
Participant's death subsequent to an Exercise Date on which the option is
exercised but prior to delivery to such Participant of such shares and cash. In
addition, if permitted by the Administrator in its sole discretion, a
Participant may designate a beneficiary who is to receive any cash from the
Participant's account under the Plan in the event of such Participant's death
prior to exercise of the option. If a Participant is married and the designated
beneficiary is not the spouse, spousal consent may be required by the
Administrator in its sole discretion for such designation to be effective,
unless otherwise required by applicable local law.

(b) If the Administrator in its sole discretion has permitted the Participant to
make a beneficiary designation, the Participant may change such designation of
beneficiary at any time by written notice. In the event of the death of a
Participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such Participant's death, the Company will
deliver such shares and/or cash to the Participant's spouse, if any, and if
none, to the Participant's estate.

8

--------------------------------------------------------------------------------

(c) All beneficiary designations permitted under this Section 9.04 will be made
in such form and manner as the Administrator may prescribe from time to time.

9.05 Adjustment upon Changes in Capitalization; Change in Control.

(a) Adjustments. In the event that any dividend or other distribution (whether
in the form of cash, Common Stock, other securities, or other property),
recapitalization, stock split, reverse stock split, reorganization, merger,
consolidation, split-up, spin-off, combination, repurchase, or exchange of
Common Stock or other securities of the Company, or other change in the
corporate structure of the Company affecting the Common Stock such that
adjustment is appropriate to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Plan, the
Administrator shall adjust the shares of Common Stock to preserve the benefits
or potential benefits under the Plan. Action by the Administrator may include
adjustment of: (i) the number and class of Common Stock that may be delivered
under the Plan, (ii) the Purchase Price per share, (iii) the number of shares of
Common Stock covered by each option under the Plan that has not yet been
exercised, and (iv) the numerical limits of Section 6.01.

(b) Change in Control. In the event of a Change in Control, any Offering Period
then in progress will be shortened by setting a new Exercise Date (the "New
Exercise Date") on the date of the Change in Control and will terminate on such
date, unless provided otherwise by the Administrator. The Administrator will
notify each Participant in writing, at least ten (10) business days prior to the
New Exercise Date, that the Exercise Date for the Participant's option has been
changed to the New Exercise Date and that the Participant's option will be
exercised automatically on the New Exercise Date.

9.06 Notices. All notices or other communications by a Participant to the
Company or the Administrator under or in connection with the Plan will be deemed
to have been duly given when received in the form and manner specified by the
Company or Administrator at the location, or by the person, designated by the
Company or Administrator for the receipt thereof.

9.07 Conditions Upon Issuance of Shares.

(a) Shares of Common Stock will not be issued with respect to an option under
the Plan unless the exercise of such option and the issuance and delivery of
such shares pursuant thereto shall comply with all applicable provisions of law,
domestic or foreign, including, without limitation, the Securities Act of 1933,
as amended, including the rules and regulations promulgated thereunder, the
Exchange Act, and the requirements of any stock exchange upon which the shares
may then be listed, and will further be subject to the approval of counsel for
the Company with respect to such compliance. If, on the Exercise Date of any
Offering Period, as delayed to the maximum extent permissible, the shares of
Common Stock have not yet been issued, all payroll deductions/contributions
accumulated during the Offering Period (reduced to the extent, if any, such
deductions/contributions have been used to acquire shares of Common Stock) shall
be distributed to Participants, without interest, unless otherwise required
under applicable local law.

(b) As a condition to the exercise of an option, the Company may require the
person exercising such option to represent and warrant at the time of any such
exercise that the shares are being purchased only for investment and without any
present intention to sell or distribute such shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law.

9.08 Covenants of the Company. The Company shall seek to obtain from each
federal, state, foreign or other regulatory commission or agency having
jurisdiction over the Plan such authority as may be required to issue and sell
shares of Common stock upon exercise. If, after commercially

9

--------------------------------------------------------------------------------

reasonable efforts, the Company is unable to obtain from any such regulatory
commission or agency the authority that counsel for the Company deems necessary
for the lawful issuance and sale of Common Stock under the Plan, the Company
shall be relieved from any liability for failure to issue and sell shares of
Common Stock upon exercise unless and until such authority is obtained.

9.09 Effective Date. The Restated Plan shall become effective as of its adoption

Common Stock, and shall continue in effect until the earlier of the date that
(a) the shares of Common Stock reserved for issuance have been depleted, and (b)
the Restated Plan is terminated under Article VIII.

9.10 No Employment Rights. The Plan does not, directly or indirectly, create in
any person any right with respect to employment or continuation of employment by
the Company or any Related Company, and it shall not be deemed to interfere in
any way with the Company's or any Related Company's right to terminate, or
otherwise modify, any Employee's employment at any time.

9.11 Severability. If any particular provision of the Plan is found to be
invalid or otherwise unenforceable, such provision shall not affect the

extent permitted by applicable law, the Company may deliver by email or other

securities law) and all other documents that the Company is required to deliver
to its security holders (including without limitation, annual reports and proxy
statements). To the extent permitted by applicable law, a Participant may submit
his or her payroll deduction election or other forms by electronic facsimile or
other method of recording of the Participant's election or signature in a manner
that is acceptable to the Administrator.

9.13 Treatment of Non-U.S. Participants. Participants who are paid in foreign
currency, and who contribute foreign currency to the Plan through contributions
or payroll deductions will have such contributions converted to U.S. dollars.
The exchange rate and method for such conversion will be determined as
prescribed by the Administrator. Each Participant shall bear the risk of any
currency exchange fluctuations (if applicable) between the date on which any
Participant contributions are converted to U.S. dollars and the following
Purchase Date.

9.14 Eligible Persons in Other Countries. Without amending the Plan, the
Administrator may grant options or establish other procedures to provide
benefits to Employees who are not U.S. Employees on such terms and conditions
different from those specified in the Plan as may, in the judgment of the
Administrator, be necessary or desirable to foster and promote achievement of
the purposes of the Plan and shall have the authority to adopt such
modifications, procedures, subplans and the like as may be necessary or
desirable (a) to comply with provisions of the laws or regulations or conform to
the requirements to operate the Plan in a qualified or tax or accounting
advantageous manner in other countries or jurisdictions in which the Company or
any Participating Company may operate or have employees, (b) to ensure the
viability of the benefits from the Plan to Employees employed in such countries
or jurisdictions and (c) to meet the objectives of the Plan.

9.15 Governing Law. Except to the extent superseded by the federal laws of the
United States, the law of the State of Delaware, without regard to its conflict
of laws provisions, will govern all matters relating to the Plan. Participants,
the Company, a Participating Company, a Subsidiary, the Parent, and any
Affiliate each submit and consent to the jurisdiction of the courts in the
Commonwealth of Massachusetts, County of Worcester, including the Federal Courts
located therein, should Federal jurisdiction requirements exist in any dispute
or action brought to enforce (or otherwise relating to) the Plan.
