than standard infrared diodes.

Keep the output facet (which emits light) dry. If you store the unit in a high humidity, the optical coatings
can be damaged and render the diode useless.
Operating the laser diode at a temperature lower than recommended will usually slightly increase theoutput power (higher efficiency) and improve lifetime.

Operating the laser diode at a temperature higher than recommended will increase the threshold current
and decrease the slope efficiency.
Laser diodes need to be operated with an approved power supply/driver or they may be damaged and/or
destroyed quickly. Off-the-shelf drivers can deliver a high spike of current at turn-on, and they can deliver a
very short duration reverse biasing when the unit is turned off. Either of these will damage and/or destroy
the diode laser.
The power supply/driver should be current-regulated and specifically designed for laser diodes. The power
supply should create no surges or spikes, no reverse voltages and should not have any ringing. Many poorly
designed power supplies have voltage transients during turn-on, turn-off, or in the case of power failure.
Never make the connection to the laser diode with the power supply voltage on. Most laser diode power
supplies have provision to disable the supply and short the output to allow for connection of the diode.
Laser diodes are very sensitive to damage by electrostatic discharge (ESD), or other voltage transients. The
laser should be handled using static-safe procedures when it is taken out of its static-protective shipping
container. When the laser is not connected to a power supply, the user should short the anode and cathode
together to prevent static damage.
Some laser diodes are susceptible to damage from back reflections into the device. This is more the casewith lower wavelength material than with higher wavelengths. Thus, if attempting to collimate the output,
care must be taken to avoid back reflections.
The emission wavelength changes with temperature: the wavelength changes about +1 nm for every 6° C
increase in temperature. This value varies by wavelength.

• Heat: This is the biggest cause of field failures.
LDX Optronics Inc.
• Some laser diodes are more sensitive than others to the operating temperature. Red laser diodes tend to be

ThermalManagement ••Precautions: •more temperature sensitive than the infrared laser diodes.
Many customers do not appreciate the importance and/or the complexity of removing waste heat.
Because operating temperature has a strong influence on laser lifetime, the heatsinking of the laser package isof tremendous importance and doing it well is not as simple as many assume it is.
Waste heat must be removed efficiently and instantaneously, or the laser will heat up and burn out, or, as aminimum, experience an abbreviated lifetime.

• The laser can be operated at higher temperatures than recommended, but the lifetime of the laser is reduced
exponentially as the operating temperature is increased.

• The diode package should be attached to a heatsink plate at least several millimeters thick.
• The heatsink must be capable of dissipating the waste heat generated by the laser diode. High power laser
diodes are typically 10 – 50% efficient at converting electricity into light. The remainder of the electrical input
power is dissipated as heat. Therefore, there may be several watts of waste heat generated by the laser.
Because so much heat is generated within the small area, it is critical that the laser is securely connected to an
adequate heatsink• The best heatsink material is copper, but aluminum is also a fair heat conductor. If aluminum is used, thesurface should not be anodized in the region where the laser package makes contact with the heatsink. The
aluminum oxide anodized coating makes an effective thermal insulator.

• The surface of the heatsink should be machined flat and smooth where it will contact the back of the laser
package to allow for efficient heat transfer.

• Thermal compound, or an indium foil washer can be used to reduce the thermal impedance of this interface.
Our experience is that indium foil offers negligible improvement over a good copper-to-copper interface. In
permanent installations, some improvement of the heatsinking can be achieved using a silver-filled epoxy at
this interface. If silver-filled epoxy is used, it should be a “space qualified” low outgassing. To avoid
contamination of the laser facets (Epoxy Technology H21D, for example)• The heatsink may be cooled by air, water, or thermoelectric coolers. Depending on the type of laser, an aircooled heatsink may provide sufficient cooling, as long as the application does not require stability of the laser
wavelength and output power. Most often, active cooling of the heatsink must be used. Active cooling usuallyis either water-cooling, or thermoelectric coolers (TEC’s).

• Finally, when testing out a heatsink configuration, it is wise to test the temperature drop between the laser
package and the heatsink using a very small thermocouple touched against the base of the package. The
temperature drop during laser operation should be only 1-2 ° C.

protected from any mechanical contact. The exposed laser facets (mirror coatings) must not be
contaminated with any foreign material. Facet contamination can cause immediate and permanent
damage to the laser. You should not blow on the laser, or expose the laser to smoke, dust, oils, or adhesive
fumes.
2. The laser facets are sensitive to accumulation of dust. When the laser is operating, dust particles tend to be
attracted to the laser facet. As the dust particles enter the intense optical field at the laser facet, they burn,and the residues accumulate in the laser facet. Unless the laser is operated in a true “class 100” clean-room
environment, this dust accumulation will occur, even in a seemingly clean “lab environment. This kind ofcontamination does not occur very rapidly, but over several hundred hours of operation in a normal room
environment, an open heatsink laser will show tiny “specks” on the lasers facet under microscopic
examination. These will gradually degrade the laser prematurely. If an open heatsink laser is to be operated
outside of a clean-room for more than short periods, it should be packaged within a sealed container toprevent this dust accumulation. This does not require a true hermetic sealing of the laser. An epoxy seal oro-ring seal around the laser assembly is perfectly sufficient.

C-Mount Package:
1. To operate, the C-mount must be screwed down securely to a heatsink using a #2-56 (English) or M-2(metric) screw. The C-mount has a swallow counterbore around the mounting hole, for applications which
require close mounting of a component in front of the laser. A shallow binding head screw, or a button
head cap screw can be used in this situation.
2. Thermal grease should not be used with a C-mount. Most thermal greases tend to “creep” and the material
will eventually contaminate the diode facets.
3. The copper C-mount is the laser diode anode (+) terminal, so the power supply anode connection is best
made to the heatsink. Do not attempt to solder directly to the copper C-mount. The laser diode cathode (-)
terminal is the wire lead attached to the C-mount. Connection to this lead can be made either by soldering,or by using a small, high quality, spring contact socket. The best sockets of this type have four contact
fingers, and the fingers are gold-plated (see for example parts made by Mill-Max).
4. Great care must be used if soldering to the cathode wire lead. The soldering is best done with the C-mountalready attached to the heatsink. This will prevent the body of the laser from heating up excessively. The
cathode lead itself can withstand high temperature, but the main part of the laser.

C-Mount Package: (cont)block must remain <120°C. During soldering, the laser can also be damaged by contamination of the laser
facets with solder flux fumes. Typical rosin-core electronics solder generated a cloud of smoke when it ismelted. This smoke will coat the leaser facets, and if the laser is then operated, permanent facet damage canoccur. If it is necessary to solder near the leaser diode, the diode should be covered to prevent thiscontamination. One method is to use a piece of aluminum foil to loosely cover or block-off the area aroundthe leaser chip. The chip and the wire bonds are very fragile, so the foil must be applied carefully, without
actually contacting the laser chip.

2. Thermal grease should not be used with open heatsinks. Most thermal greases tend to “creep” and thematerial will eventually contaminate the diode facets.
3. Attaching these open packages to a heatsink is critical. This can be accomplished by either using a lowtemperature solder or a silver-filled epoxy at this interface.

Packages:

1. It is important for good heat extraction from the 9mm laser package that the Copper portion of the basemust be in good contact with the heatsink.
2. Not all parts of the 9mm package are made of Copper. See below drawing 1, which indicate the Copper
portion of the base. The window cap, and the portion of the base to which it is attached, are made of
Steel, which is a poor thermal conductor.

TO-3 Package, HHL Package and other sealed packages
1. The package must be screwed down to a heatsink that can dissipate the heat generated by the laser andthe TE cooler, if installed.
2. The heatsink should be cooled well enough that the temperature rises to no more than 40-45°C during
operation.
3. The surface of the heatsink should be machined flat and smooth so that the base of the package is notbent when the screws are tightened. Screwing the package to a heatsink that is not flat could potentiallyfracture the TE cooler inside of the package.
4. A layer of thermal grease between the package and the heatsink is suggested to improve the heatdissipation. When using thermal grease, tighten the mounting screws gently at first to allow excess
grease to squeeze out the edges.
5. The laser chip is oriented so that the wide dimension (i.e. 150um) is along the x direction, The narrowdimension (I.e. 1um) is along the Y directions.

5. Special care needs to be taken with fiber pigtailed laser diodes. The fiber should not exceed theminimum bend radius of the fiber. The minimum bend radius is defined be the fiber type and core
diameter.
6. Typically the fiber is terminated with a SMA connector. The cap should be replaced if the laser is not inuse. The end of the fiber is very susceptible to damage if it is not handled correctly. The fiber end
should be inspected prior to starting the laser. Insure there is not particles on the end of the fiber. All
particles on the end of the fiber will become damage spot once the laser is turned on.
