My New HeNe

[aryntha]

Are there any numbers -at all- on whatever tells you it was made by PMS/REO? (odd, writing this post less than a mile from PMS/REO right now...)

Maybe with a flashlight or mirror, or digicam with flash you could get that model no.? Most of these tubes should be like "30xxx".

LTYR-0200M That's the model. And it's an REO. Serial: a135a-4794-70. made november 1994

 

[aryntha]

It's 594 then.

REO's model numbers go like this:

L: (Laser)
T/H: (Tube/Head)
R/G/O/Y: (Color) (Red/Green/Orange/Yellow)
R/P: (Polarization: P - Linear, R - Random)
-
###: (Minimum output power - i.e. 0150 = 1.5mW min, 0200 = 2.0mW min)

So, LTYR-0200 says its a Laser Tube, Yellow (594), Randomly Polarized, at 2.0mW minimum (5.0mW maximum.)

For another example, their LHGP-0151 is a Laser Head (complete cylinder), Green (543nm), Linearly Polarized, 1.5mW minimum.

594 is by no means a 'bad find' though....

Well at least we solved that!

Heh, yes but man, a free yellow HeNe? WITH power supply? And optics? That's a hell of a score. Especially if it meters high, and those REOs, it may.

 

[BennyF]

whats considered high for a HeNe?

 

[aryntha]

Tubes of those length usually meter 2-3mW. ~2.5 for a 594nm would be average and strong; if you see 3-5mW out of that, that's rather high.

REOs are good stuff too, what you've got there is the Rolls Royce or Bentley of HeNe lasers.

Speaking of which, here's where I was standing the other day at around 1pm with my smartphone:

I'm literally a 45 second walk from REO when I'm doing work at the SA Center (SACD production) in Boulder.

... I was tempted to walk in and ask them about 612's.

... But then I wondered if they'd call the police.

I may at some point; call ahead and ask if I can come in and see their setup and ask some questions. Wonder if they'll go for it....

I dunno. You'd be surprised who I've been able to chat with. I dropped an email to someone in photonics research here that showed them that I know what I'm talking about (for the most part) and that I was really interested in their field. I ended up having lunch with them, getting a tour of the lab, and some really interesting information.

I vote you talk to them!

You know, i'll give it a shot. The worst they can say is no. The best they can say is "Oh, 612s? We've got those!".

I'll start with some emails and see where it goes.

Sounds like fun let us know how it turns out.
