    Default University Labs / Spectra-Physics He-Ne

    More weekend laser porn! This one's a c1970 University Labs model L241 with the Spectra-Physics name on the power supply and an S-P tag on the bottom. University Labs was formed in 1966 by Tom Perkins, the "Valley Boy" of silicon valley venture capitalist fame. He partnered up with electrical engineer Richard Jaenicke and Henry Rhodes, a glassblower with a shop in Berkeley, CA on University Ave. The loft above was divided into three spaces: the center one for Perkins' office, on the left was an artist making paper mache psychedelic gorillas, and on the right was Augustus Stanley Owsley III who was heavily into the production of LSD (still legal at the time).
    I have about ten of their lasers in the collection. They eventually sold the company to S-P, and this is apparently one made during the transition. It features a collinear aluminum cathode, unlike the dual neon sign cathodes of their earlier tubes.

    that tube is a work of art... does it function?
    suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

    Nope. Here's their earliest version of the "Lasertron" tube. Notice the use of beakers as raw material for the tube. One can see the mL markings on the sides! This tube was given to me by Professor Tony Siegman of Stanford, shortly before he passed away.

    i remember seeing beautiful old hene tubes at my physics department. they're just wonderful little things. my favorite lasers.

    do you know why it does not work? I have been told that the helium still finds a way to leak out of a sealed tube, i wonder is that is true or not
    Polk SDA SRS, Parasound HCA 3500, Luxman M117, Onkyo 504, 7.62X39, sometimes a ball on a string is the greatest of toys for us nonhuman types. oh and some lasers, lots of lasers
