Been a while since I've posted about an old laser, so here it is. This one's different though. It's a demonstration model of the first gas laser made by Bell Labs in 1960. Probably made in 1966 by Bell Labs for a trade show, this device features a cut-away section showing the rear mirror mount design, an operational red-tinted neon tube in the center, and a flashlight bulb mounted in the output mirror mount. There's a focusable insert for the output mirror mount that holds a lens and red filter, to make a simulated red spot of light at some distance. So, not a laser but a wonderful addition representing the very first He-Ne laser built. It comes to me via Sam Goldwasser and Phil Bergeron.
