Laser Modules Series 5MC

The laser has integrated electronics for control of the laser output power. The output power can be controlled using the modulation input ports TTL and analog (TTL only for electronics type B) or manually using the potentiometer. 

Using the potentiometer you set the maximum output power of the laser. Turn the potentiometer clockwise for more power and anti-clockwise for lower power.

For all lasers with analog modulation input: The input for analog modulation allows applying an analog voltage U_analog, which allows a linear control of the laser output power from approximately zero up to the maximum power given by the potentiometer setting.

Please refer to the manual for more details.

No, you are not allowed to take off the attachment optics. If you do so you can severely damage the laser as well as hurt yourself and others around you.

Each modification of the laser needs to be discussed with Schäfter+Kirchhoff first and is not to be done by the customer.

Often higher power lasers can be equipped with internal optical filters to reduce the laser power, which in consequence may mean a smaller laser class. 

This option has the advantage, that you can still set the laser power using the potentiometer and - if the laser has an analog modulation input- use the full range of the analog modulation input for setting the laser power. 

Please note, that reducing the laser power by potentiometer or analog modulation input so that it operates close to the laser threshhold negatively affects laser features like pointing stability, line width/spot size or state of polarization.

Please contact Schäfter+Kirchhoff for lasers with reduced laser power.
