Helium-Neon laser inverter power supply
Hi Dennis:
I couldn't remember... but finally did.
There is the defacto go to FAQ... for "gas laser tube nuts" called "Sam's Laser FAQ" ... there is good bit of information about He-Ne laser power supplies, et. al. (No relation to the schematic service, for T.V. repair... and not a quack [ is/was a prof. and has a PhD, if that precludes that sort of thing.] )
Gas discharge laser tubes are similar to "spectrum discharge tubes" ... at least the spectrum tubes I'm familiar with.
There's several scientific supply houses, in the U.S. that sell those spectrum tubes (but, I think they are all made in China.) The tubes I'm thinking of are about a foot long, have cold cathode electrodes on either end, and are made of glass.
