The laser was 30 years old at the time and kept in expectation that it would go to a museum, perhaps to the Smithsonian or equivalent. I didn't use it in my work. My advisor's retired technician would still come in once every couple of weeks because of his love for the Labs. Towards the end of my stay he and I put in fresh gas tanks and fired it up. All the 1960s vintage glass, power supplies, mechanical and optomechanical systems worked and it lased like a champ and made firebrick beam dumps glow.
