interesting megawatt green laser

[Skyko]

I am in the process of parting out a Coherent versapulse since it did not sell as a complete unit on ebay (no bids at $1800). I am actually kind of glad, since I really wanted to examine it further.

I have removed two of the pockels cell q-switches (Inrad PLC01 and Inrad PKC21) and was thrilled to find two modular high voltage drivers hiding under a bracket which are matched to these q-switches! They are Analog Modules Inc. 532-1-EXT and 820-71. They seem to run off 15VDC according to the label. I uploaded a pic to photonlexicon here:

There are 3 lasers in the device, two 1064nm flashlamp pumped bricks and one 755nm alexandrite flash lamp pumped brick. The label lists the max output as 3000mJ at 10mS 532nm, 400mJ at 7nS 532nm, 800mJ at 8nS 1064nm, and 1000mJ at 10nS 755nm.

I have identified the beam path and KTP? location of one of the 532nm lasers. It seems to be a folded optical path. There is a galvo which seems to block the 532nm section of the beampath. It does not have a part number, but I can't believe it would be fast enough q-switch that laser at 7nS? It has been (carefully) removed in this picture to examine it, but you can see where it goes in the path:

A bit unsure now what to do with everything. The z-fold high power pulsed green laser seems to scream pulsed holography? I am sure the pockels cells would be usefull to someone. Ideas? I was thinking of doing a simple burn mark test of the z-fold laser with the galvo removed and the flashlamp energized with my SSY1 power supply, but I am a bit unsure of the minimum energy required and the burst energy of the lamp. I may have to dig into the very nonmodular coherent power supply and see if I can determine what the intended pump energy is for this laser.

Any opinions or advice much appreciated.

The owner of this company http://www.umlasers.com/ ''Herb'' is an expert at this laser . Ive worked on this laser system only for a day. So Im not that familiar with it. I know it uses hundreds of volts for the lamps. Grab a pen and paper when you talk to him because he gives lots of info. But honestly, If you don't have the complete system its really not worth screwing around with. He might buy the laser head of you.

Hi thanks, but I have the complete system. I will dig into the power supply to see if I can separate a useable module for the lamp(s). First glance it looks like three identical trigger modules + a bulky transformer and a ton of 450V caps. I have already made sure all the caps were discharged.

I am guessing the pockels cells and drivers are fairly pricey new?
