Chapter 4  Operation 

CAUTION! 

Always observe proper Laser safety when operating this unit.  

4.1.  Normal Operation and Use 

The unit should be located on a solid, dry working surface. If preferred, the unit 
can be secured to a standard optical breadboard using Thorlabs C1502, C1503, 
or VC3 V-groove mounts. For best performance, the unit should be oriented with 
its vent holes and cooling slots facing up. 

1.  If not already done, move the output shutter lever to the CLOSED position.

2.  With the key-lock switch set to the 0 (Off) position, connect the power supply 

to the LDM by plugging the DC Jack into the DC IN socket on the end cap 
of the module. Plug the AC connector of the power supply into a suitable 
mains socket. 

3.  Make sure the interlock shorting screw is in place. If using a remote 

interlock, see the next section for instructions on how to set up the remote 
interlock.
