I just got a HeNe laser tube from an old 1982 Pioneer laser disc
player.
The tube specs at 1mW at 633nm. I tested this tube and at cold start I
get 1.3mW and at warm up I get 1.5mW. The tubes output seems great,
however the getter spot looks like it wasn't fully activated. It has a
slight whiteish tint, not a flakey white. Would I still be getting such
a good power reading if the getter was exhausted?
Sam Goldwasser if you read this, give me an e-mail at [email protected]
so I can send you a pic and you can tell me what you think.
