Vintage Lasers

I'm looking for the oldest lasers I can find, and thought those reading here might have come across one or two when looking for old astronomy related equipment. Please contact me if you have! Names that would be associated with them would be Trion, Hughes, Raytheon, Optics Technology, Maser Optics, Perkin Elmer, Spectra-Physics or Lear Siegler. Thanks!

I think that there's a Spectra Physics on Ebay under scientific instruments.

I am not sure what sort of lasers you are looking for, visible wavelengths? How big a laser are you willing to deal with? We have a couple of the old Argon-Ion 5 watt jobs. Spectra-Physics or Coherent. If I am not mistaken, one of them required 50 or 60 amps of 208 three-phase plus continuous cooling water.

I would think that the Surplus sales departments at Universities would be a good place to look...

How old would a vintage laser be? I have an 18" Uniphase He-Ne tube that I have had for quite some time and was used when I got it. I wouldn't say it was "vintage". Just old! But I don't know much about lasers either.

Thanks for the replies guys! Sorry for my absence. I'm a collector of lasers from the '60s, which are very hard to find anymore. Most from then are still small, usually small rubys or He-Ne. An exception is the '69 Hughes Argon Ion laser I just found, shown below. The head is only 28" long but the power supply is comically heavy. An enormous transformer hiding behind that 5" knob!

This is easily one of the top few inventions of the last century, and the earliest examples (from the Kennedy years) are quickly slipping into the trash.
