Hi there!!
Last weekend I picked up two coherent 900 series krypton-ion lasers from a a club, which upgraded to DPSS a couple of years ago.
The system has been converted by Laserimage in 2001 for show use, adding PCAOM's and refilled with Krypton.. from what I read off the stickers i believe the system initially was built using argon.. is this correct?
It has been used from 2001 to 2008 on a weekly basis, only 3 hours per weekend. It has had regulary maintanence in this period. During the last maintenance in 2008 the power has been measured at 5.9W and 6.1W all lines.
In 2008 the venue upgraded the lasers to DPSS. The PCAOM's and fiber launchers were removed.. but the lasers remained untouched.. until now
Here are some pictures:

The outside with some controls and labels
Details of the tube. Looks like an Coherent I-90
System #2:
closeups of the tube
And the label of the second tube.. even older than I am
There are also 2 3-phase transformers so the machines can be fed from european outlets.
I can't wait to fire them up. There is a step-by-step instruction sheet included, which tells me to start the system up, wait 2 minutes, slowly turn the beam to 40 VOLT/AMPERE, wait for another 2 minutes.. etc.
don't have the sheet right here but I'll post the exact instructions here later..
As there is no running water in the workshop I'll find myself a pump and bring a huge amount of water, and build a closed cooling circuit. Is there a minimal water pressure level I should respect?
Now As the system hasn't been touched in 4 years.. what steps should I take before even thinking about powering it up?
I read the tube pressure should be sufficient, or else the PSU might blow.. where can I check this?
I'm afraid something like this will happen: http://www.youtube.com/watch?v=V4gOg-TESKk
I know there are some of you very experienced with this equipment.. I'd very much apreciate your input!
Thanks!
