Laser Operation

Switching the laser “on”
1

Ensure the mpc6000 is not powered (i.e. 24 V DC source is switched off).

2

Connect the Laser Umbilical Cable to the port marked ‘Laser Umbilical’ on the mpc6000 before connecting the otherend to the laser head. Tighten the locking posts on the screws at both ends so they are finger tight.

3

Switch on the 24 V DC source, this should illuminate the mpc6000 green power LED. At this stage the thermal control
circuitry is activated but no laser emission should occur.

4

The analogue Control port (see Figure 4.2) is multi-functional as it has connections for Interlock, Enable Switch andLaser Power Control/Modulation. The Interlock must be closed to allow the laser to operate, and this can be achieved
using the supplied green-spot Interlock Dongle.

5

With the Key Switch turned to the ‘on’ position, a momentary press of the Enable button will start the laser.

Warning: Serious Personal Injury
If a red spot Interlock Dongle has been supplied with the laser system this will over-ride the need to press the Enablebutton. Turning the Key Switch to the ‘on’ position will start the laser.
6

Using the Encoder and Menu Up/Down buttons (see Fig 4.1) the operation current or power can be adjusted (seeSection 5: Front Panel Controls).

The laser power is constant, and a feedback control loop removes noise (Electronic Noise Reduction/Pure Technology) andmaintains the power at the level requested by the operator via the Front Panel LCD. Note due to the implementation ofElectronic Noise Reduction the power will be stable close to the requested power but may not be exactly at the requested
power. Following the description in the Recalibrating the Laser Power section may bring the power closer together if this isrepeated a few times.

Switching the laser “off”
The laser is switched off by turning the Key Switch to the ‘off’ position or disabling the interlock connection. The opus system MUST NOT
be positioned so that it is difficult to operate the disconnecting devices.

In order to adjust the laser output, the user must first select the parameter mode displayed on the LCD screen by pressing th emenu down button. This action changes the text to the navigation color blue. Depressing the menu down button again willchange the text to the selected color red. The rotary encoder allows the selection of the required parameter (power orcurrent). Once selected, depressing the menu up button once will return the parameter back to the navigation color blue. The
laser is now operating in the selected mode.
Using the rotary encoder select the parameter power or current, depending on selected mode. Depressing the menu down
again will change the selected color red. The value can then be changed using the rotary encoder. The value will change faster
if the rotary encoder is depressed whilst rotated.

Once the desired value is reached, depressing the menu up button

LASER OPERATION

Control Port - Functionality
The MPC6000 can be operated directly via the control port (see Figure 4.2) by applying 0 to 5 V, interlocks and push button inaccordance with the diagrams in this section. Alternatively, the supplied dongle (interlock plug) will allow the system to be
operated without external interlock connection.

Within the interlock circuitry there are several connections that control different aspects of the system that can be used tosafely shut down the system. These can be used as part of a laboratory interlock safety circuit. If the interlock is broken thesystem will shut down and the Enable button must be pressed to restart the system. These are outlined below with reference
to the interlock connector and the diagrams below.
•

Pin 6 and Pin 5. This is the main interlock connection, and this connection is required for the system to be operated.
Should the closed loop become broken, the laser will be deactivated, and laser emission will cease [Fig 5-1].

•

Pin 5 and Pin 7. This is the laser emission indicator line. It is recommended that this is connected to a LED which will be
lit if the laser is enabled (switched on) [Fig 5-1].

•

Pin 3 and Pin 8. This is the enable push button connection. If the interlock and 5V line (Pin 1 to Pin 4) connections areclosed, then momentarily pushing the enable button will enable the laser.

•Pin 1 and Pin 4. 5V needs to be supplier to pin 4 for the laser to operate. The PSU has its own 5 V source (pin 1) whichmust be shorted to pin 4 to allow full Power Mode operation [Fig 5-3]. If this connection is broken the laser will bedeactivated and laser emission will cease.

The following points need to be considered when using this connection as part of a laboratory interlock safety circuit.
•

Connections to the control port shall be “potential free” i.e., isolated from mains voltage by a barrier rated at 3 KV(e.g., Double Insulation, Etc.).

•

The combined electrical resistance of the “Enable Switch”, “Interlock” and associated wiring shall be less than 5 ohms.

•

If a solid-state device such as an opto-isolator is used as the switching element(s), the total combined voltage drop
must not exceed 500 mV.

PAGE | 15

LASER OPERATION•The current through the “Interlock” and “Enable Switch” circuitry is less than 100 mA. The LED current source is 10 V
via a 540 R resistor.

Diagrams of the 9-way D-type interlock connector are shown in figures 5-1, 5-2 and 5-3.

Figure 5-1

Figure 5-2

Figure 5-3

It is recommended that a red LED is always connected between pin 5 and 7, to show when the laser is active.
The minimum connections that need to be made for the system to be operated are•Pin 6 to Pin 5•

Pin 1 to Pin 4

Then closing pins 3 to 8 momentarily will start the system.

RS232 Port – Functionality
Control of the laser can be achieved via the RS232 port using a terminal emulator such as HyperTerminal or PUTTY. This allows
the operator to:• Turn the laser on/off.
• Control the laser power.
• Prompt the processor for information such as laser head/PSU temperature.
• Check the laser status.

It is necessary to have the Interlock switch closed via the Control port to enable the laser. If the Enable switch is open theenable button on the front of the mpc6000 needs to be pressed momentarily to enable the laser, even if the laser is controlled
through the RS232 port. If the Interlock and Enable switches are closed via the Control port, the laser will enable without
needing to press the enable button when controlling the laser through the RS232 port. Pins 1 and 4 of the Control port must be
shorted together to allow maximum current to be set by the RS232 commands.

The RS232 port uses the standard 9-way connector pin configuration:
Pin 2 TXD: RS232 – Transmit
Pin 3 RXD: RS232 – Receive
Pin 5 GND – GroundLASER OPERATIONPAGE | 16

Port settings are:Baud Rate: 19,200
Parity: None
Stop Bit: 1
Hand Shaking: None

The operator must wait for a response from the PSU before sending the next command. A response is any text string (includingnull) followed by a carriage return, Line Feed.
The system has been tested for compliance using 3 m long serial cable. If a serial cable of over 3 meters in length is usedcompliance of the system may be compromised. Therefore, it is recommended that if this is required, optical isolation should
be used.
Note that most PCs do not have an RS232/Serial port as standard so a UST to Serial (RS232) adapter (sold separately) is neededthat is able to go to the full RS232 voltage levels for the connection to function correctly. For recommendations on adapters ormore information please contact your sales representative.

LASER OPERATIONPAGE | 18

RemoteApp
Using our unique RemoteApp software suite the laser can be controlled via the RS232 port. It can be downloaded fromwww.novantaphotonics.com. Follow the on-screen prompts to install the software onto the computer. RemoteApp includes acomprehensive instruction manual which can be accessed via the ‘Help’ and ‘Contents’ tabs.
The RemoteApp can also be used if a remote connection is required by our Service & Support Centre and is a powerful tool if
performance optimization is required.

Re-calibrating the laser power
The laser can be recalibrated at any time during its use to ensure the APC mode is in good agreement with any external power
meter device. Recalibration is a simple process that takes place via the RS232 port. The procedure for recalibration requires theRS232 port to be configured for use with a terminal emulator. The following procedure must be followed:

1

Select an intermediate power that the laser is capable of reaching. Set the laser to this power by typing the command
POWER=###. “###” represents this intermediate or characteristic operating power level in mW.

2

After a period of 5 minutes, measure the actual power using a trusted, external power meter.

3Type the command ACTP= [external power meter reading in mW].

4

Confirm that the laser has adjusted its power such that the external power meter now reads ###mW within a few
mW.

5

If necessary, repeat steps 3 and 4 until the calibration agrees.

6

Once accepted, type the command WRITE to store the new calibration.

Important Note: Take extra care to remove back-reflections to the laser. Any magnitude of back reflection may
disturb the resonant cavity and will affect the APC feedback control loop.

COOLING REQUIREMENTS AND POWER CONSUMPTIONPAGE | 19

Cooling Requirements and Power Consumption
Cooling Requirements
The laser has a characteristic warm-up period before it reaches specification; this time depends partly on the heatsink to which
it is attached. However, the typical warm-up time is 10 minutes from switch on.
In order for the laser to perform to specification, it must be adequately heatsinked to the base of the laser. Operating the laser
on an inadequate heatsink will adversely affect its stability and may result in thermal shutdown of the laser or reduction in
optical power. An additional cooling aid might be required (e.g. TEC, forced air cooling, water cooling). Operating the laser on awater-cooled plate mounted to an Aluminum optical bench should produce optimum performance, provided the specificationsof the chiller connected to the water-cooled plate are sufficient to handle the heat load of the laser. The user should consult
the Power Consumption section of the user manual where the power consumption figures presented can be used as a first
approximation of heat-dissipation. Examples of heatsinking solutions are shown below (with a gem laser, but the same
principle applies for the opus). For further information on heatsinking, please consult your sales representative who will beable to provide a heatsink solution.
Water cooled heat sink.

POWER CONSUMPTION

opus laser headOnce the maximum operational temperature for the laser head (see Introduction Section) has been reached, one of two things
will occur: To ensure the correct cooling arrangement the flow direction should be as follows:1

The current to the diode will immediately be switched off and the laser system will need to be restarted once thetemperature has been restored to normal.

2

If de-rating is enabled the current will gradually be reduced to zero in order to try to allow the laser head temperature
to stabilize. If the current does reach zero, the system will need to be restarted. The effects of de-rating are shown in
the table below:

A similar arrangement occurs for the PSU once the maximum operating temperature (see Introduction Section) has beenreached.
Important Note: The indicator LED in this instance is marked ‘PSU OVERTEMP LED’.

Power Consumption
The power consumption shown is that which is drawn at the plug from the mains supply in both the Maximum and Typicalstates. The Maximum power will usually be drawn at start up and the typical power is when all temperatures are stabili zed, andthe system is operating at the specified power. Peak values are shown in all cases and efficiencies will vary between systems ofdifferent wavelengths.
Maximum at 240 V supply – using the supplied External Power Supply Source:
250 W
At the 24 V input the MPC6000 can draw maximum of 10 A. Typical current draw is 4.5A in the steady state.

LASER MAINTENANCE

PAGE | 21

Laser MaintenanceIf the opus is operated in a smoky or dirty environment, occasional cleaning of the laser window may be necessary. To perform
this procedure, the laser must be turned off and, using optical cloth dampened with research grade methanol, the laser
window must be gently wiped.

•

Always follow the instructions given in this Operating Manual•

Always use the PSU which was delivered with the laser and do not attempt to control the laser with any other PSU.

•

Ensure laser is firmly fixed to an appropriate heatsink to allow efficient heat dissipation from the laser head andensure a thermal equilibrium is achieved. The laser should be held in an environment with temperature stability±0.1°C to achieve the marketed specifications. Use the laser head power consumption figures to help determine what
heat-sink dissipation is needed or speak with your sales representative.

•

Never touch the connector on the laser head with anything other than the Umbilical cable provided and always follow
the connection instructions in this Operating Manual•

Do not open the laser head or PSU; this will immediately invalidate the warranty.

•

Do not subject the laser head to mechanical shock, if severe this can cause misalignment of the laser cavity.

•

Do not allow the output window of the laser to be touched as this may damage the precision optical coatings used.
Avoid very dirty atmospheres where dirt may settle on the window.

•

Do not operate or store this laser system in very humid or damp environments.

Guaranteed specification will only be achieved at the ordered power level. Laser calibration may not always be accurate at very
low powers – for alignment purposes seek external attenuation.
