An Endurance FAP800 (COHERENT) 808 nm infrared laser module (TEC cooler, optical system, laser driver with build-in power supply.


Endurance uses FAP 800 infrared (808 nm) Coherent laser modules with different laser output (15 / 25 / 40 / 50 watt) converting them into powerful industrial laser attachments that are compatible with all CNC / plotters and most 3D printers.


Our improvements in the FAP 800 infrared Coherent:

What we added to the FAP 800 Coherent laser control box:

  • AC/DC 2V 30-65A power supply (PSU),
  • Laser controlling driver with PWM signal (3.3-12V),
  • Endurance TEC controller system to keep the temperature around 15C,
  • Dynamic PWM module to change the laser power with a potentiometer,
  • Voltmeter + ammeter to check the laser power.

TEC cooling system

We use  12V 5A x 2 TEC cooling systems that allow keeping the laser module at an efficient temperature ~ 15C and added our own 50x50x100 aluminum heatsink.

Optical system

Endurance FAP 800 Coherent modules are equipped with a G7 laser lens installed in the SMA905 connector.

Some nuances about operating the FAP 800 laser unit

After you finished the work with the FAP laser, before turning it off completely, it is recommended to turn off the laser power (green button) and wait 5 minutes for the radiator on the laser to cool down. After that, turn off the power completely (red button).

The “+” power supply feeds the FAP laser module. . The laser head should not have contact with any other metal objects, through which the current can flow. First of all, with the frame of the machine on which it is installed. In the contrary case, the power will be lost, and the machine will stop working.

The user also needs to know that if the temperature indicator does not show anything, then the laser cannot be used, since the Peltier will not turn on and the cooling will not work.

The voltmeter, which shows the voltage across the laser, slightly overestimates the readings, approximately, by  0.2-0.3V. All voltmeters of this type turn out to be like that. The ammeter shows the current correctly.

Inside the Endurance FAP800 Laser Box

FAP800 Coherent laser box (Endurance lasers design)


The control and indication elements on the cover of the FAP and their meanings in my opinion:
1 – General food. — “Power (ON / OFF)”
2 – Laser power supply and Peltier. — “Laser & TEC Power (ON / OFF)”
3 – Volts/amperes on the laser. — “Laser Input”
4 – Volts/amperes per Peltier. —  “TEC Input”
5 – Thermal relay
Current temperature.
Set temperature.
6 – Working with PWM
Mode “0” – work from  PWM directly from the machine
Mode “1” – work from  PWM through the regulator.

7 – Regulator block. I don’t know if it is necessary to separate it and somehow sign it separately.
8 – Regulator modes.
Mode “0” – The regulator is off. Here it is clear “OFF”.
Mode “1” – The laser is always on. The power is set by the regulator.
Mode “2” – Through the PWM wires from the machine, on which there is no PWM, a voltage of 3.5-24V is supplied, through which the laser is turned on. The power is set by the regulator.
9 – The handle of the regulator. I don’t know if I need to sign it.
10 – Power indicator.
11 – LED that turns on when voltage is supplied from the machine through the PWM wires. Works only in mode “2”
