Having had past experience with similar beasts, although not Russian ones, you need a very low Xenon pressure some place between 20 and 150 Micron. Contrast that to the 250- 350 Millitorr of a small frame Argon Ion laser. I see a fill solenoid there, so I hope it has not leaked up to high Xenon pressure in the tube. They also consume gas rapidly, driving it into the bore walls, and far more rapidly then an Argon ion laser.

There are two design regimes for these beasts, at least the US made ones. Large pulse low rep rate, ie 10-20 Hz and lower fill pressures, and very high rep rate, low duty cycle, aka Britt Medical Systems, that actually emits 100-200 mW Average Power when air cooled tube and 2 watts tube when liquid cooled for up to 30 seconds before needing a cool down cycle. The only way to figure out which regime without a manual or data sheet for the laser is to analyze the pulse forming network and the measure the sync oscillator's rate

The high rep rate tubes with lower pulse energies operate in a plasma regime where CW ion lasers can't run, and the very short pulses do not heat the gas very much.

You might want to ask JSC Plasma if that is one of theirs... Beautiful unit, I hope you can get it lasing.
