I love to see these old pictures Bob, keep posting 'em.
There's something about HeNe's that i just love. Perhaps because they were the first lasers I ever owned, maybe it's the beautiful beam profile, or perhaps me using them to make my first ever holograms. I don't think this love affair is going to end anytime soon.
My biggest regret was selling my green HeNe, i'd love to pick up another one of those... and perhaps a yellow, and an orange..............
OK, I confess, i'm an addict

There is another that states that this has already happened.”... Douglas Adams 1952 - 2001
