... nom!, it's more like: "pom pom pom"

Thanks Viktor. I need to check my alphabets before posting!

This one looks just like the 1963 Perkin Elmer model 5300 He-Ne, but it's the 1984 model PG-75-1 from the former Soviet Union. Everything is here and nothing is broken so it should operate. Again, hot cathode and no magnets.

Here's a nitrogen laser head from 1987, the model ILGI-503. The tubes electrodes are clamped in the insulating mounts.

That is really cool, i love how that stuff looks and would have never know they made them different from the ones made here

Here's an Nd:YAG laser head that shows a bunch of differences from western lasers. It's a c1989 model LTI-501 according to the source. The case is cast aluminum and the sides attach with cabinet latches. Both mirrors are 50mm diameter. The front is not adjustable while the rear is in a gimball mount under the covers, with a monitor detector at the end. There's a water cooled pump chamber held in an adjustable cradle, a translating aperture, an adjustable cradle for the missing Q-switch, and a solenoid mounted shutter.

Following on from above, I have more info about what I called the model OTH-350 (post #5). Apparently it's the model LG-66, as I found a more complete sample shown below. A set of ballast resistors is included in an inline module. Also shown below is an ad for some of the lasers in this thread that appeared in Laser Focus of April, 1979.

I actually saw a running LG-72 HENE in Lithuania about two years ago... Takes a licking and keeps on ticking...

Eidetic, just watch out for those old Russian Mil PY/2PM standard connectors, they may look Mil-Spec, but they really do not meet "western" norms for multiple insertions. They are usually very fragile. Hated that part of the Euro job, especially the high powered single pin ones, which are crap...
