So, I ended up coming across this auction.
Melles Griot 05-LGR-193-497 Green 543.5 nm 1.5 mW Helium Neon Laser 05LGP193 | eBay
Melles Griot 543.5 GreeNe with power supply, 2000 MFR Date, supposedly *unused*.
$150 buy it now, but he accepted my offer of $100.
I don't know if this is the only other one he has -- he may have more.
BUT - I believe him when he says unused. This is MG's highest rated cylindrical GreeNe, "rated" at 1.5mW, but new, these almost always put out more. I have a lot of GreeNes, and I was really surprised at how visually bright this thing was at startup. Measuring it, mine's doing 2.6mW.
Now, I know, in this day and age of 1W this and 2.3W that being pleased with 2.6mW of green might seem crazy to some, but, if you're new to HeNe at 543.5, understand, that this is rather high. Green is the 'hardest line to do' in HeNe, and honestly, for $100, essentially a "new old stock" MG Cylindrical in great shape putting out over spec ...
Well let's just say, if anyone on the forum here has been longing for or even 'kinda wanting to get around to' getting a green HeNe, I would say, with the above auction: run, don't walk. This is an amazing deal even at the BIN price.
He may only have one more, I don't know (I hope he has several - because of expenses on medical stuff lately i've been a little less err, laserful, otherwise i'd get another) but -- really...I can only hope this goes to some LPF members.
