I would agree that the broken cooling head on the mirror is not related to the power supply problem. Normally, the cooling water is isolated from the high voltage supply and tap water should be fine. It sounds like you have a high voltage leak. Try turning on the power supply connected to the...

Can you provide a picture?

The power supply should have included a wiring diagram. Typically it is wired like the attached picture. The first one is the simplest circuit. Power output of the laser is controlled by the 5K pot. Don't assume this is the correct wire diagram for your power supply. Get the proper one...

Is the Lexel 95 power supply still available?

If it is only a foot long, it is probably only good for 1 to 5 watts. You could probably energize it with a 9,000 volt neon sign transformer or less. Made sure the transformer is on a Variac so that you can control the voltage.

Yes, it appears to be a sealed CO2 laser. You just need to add cooling and a high voltage power supply. How long is the tube?
