Argon Krypton

Argon Krypton Laser Tube? - eBay (item 140383663194 end time Feb-22-10 01:01:44 PST)

So, is there a 99% chance this thing is dead, or 100% chance?

I saw that too, while looking for a krypon laser.

Probably 99% chance it's dead (the 'chip' in the glass does not bode well), but this is a two-brewster tube, you'd need your own HR and OC mirror.

With stuff like that, I'm really trying to continue to tell myself, "if they say 'untested as-is', they know it's broken."

Wow, that's an interesting little tube - based on the design I imagine it was from a small air cooled system and there would be heatsink fins clamped around the ceramic portion of the tube. Chances of it working? uhh, probably very low - basing on the fact that the brewster windows are epoxy sealed and the fact that one of them is chipped. Plus the rule that one should never buy a gas laser from ebay without pictures of it working.

But hey for $9 you might have some fun poking it with HV and see what happens oke:

Omnichrome 532 Argon, the kryptons and mixed gas ones are always 632s and almost twice as long...

Thats not a bad chip, but the missing fin block and head are usually a bad sign. There was a lady dumpsterdiving Omni a few years ago and all sorts of raw tubes, some good, some bad, made it into the world.

So you are TRUELY playing the lottery on that one...
