Dear Gene,

the original question also concerned the ease of implementation of the 
laser modulation. Is it a basic TTL pulse, the ability to control an 
external shutter, embedded drivers for the control of AOM/EOM or direct 
control of the laser? This is probably the more important aspect of the 
question and will obviously be different in the case of C1 class systems 
to A1 systems.

The physical hooking up of a laser is probably less thorny than the means 
of controlling the beam when it is hooked up and I just wanted to know the 
level of preparation and work that would be required to get a fully 
functioning system and to what specification beam blanking/ROI 
functionality could be acheived.

all the best
