Don't know anything about this thing, looks like some sort of measurement device.
Looks like it could have been expensive when new. Talk about a small gas laser!!!

Do you know its a gas laser, or is that just speculation?

edit: i see now, last pic it says "helium-neon 1mW". Indeed I have never seen anything like that before...Do you have any way of powering it?

I hesitate to put power on the unit until I can get a little more info on it.
I do plan to put power to it, can wait to see that 1mw beam. LOL
 
It appears to me to be a modulated HeNe
laser. That open circuit board makes me
think -- audio.
Could be fun to send sound if it works but
I'm guessing too.

That AOM module appears to have optics
around it and may be a beam modulator cell.

The label says it's He-Ne, but where is the tube at? What is inside the black box (not the power supply, the other one)? :confused:

The little power supply wires feed down under the optical table that all the mirrors and such are mounted on. I believe it is under the optical table. Anyway thats where the output of the HV supply goes. Hard to see in the photos. The other black box is a Acousto-optic Modulator (AOM)

Any guesses to what it is???

Guess I was right about the modulator !!!! I can't see all the connections but one exterior
fitting MIGHT be optical. Long ago, I read where there was an attempt at using a long strand of fiber in a loop for navigation purposes. Perhaps this sent very short pulses through that loop. If you power up the HV supply, you may see some red laser on one side of the AOM but it may need an RF or Sonic input to open the modulator.
Interesting !!! I think GPS made this obsolete if that is what it is (was).....

Just based on the frame, it looks like it was mounted to something, possibly an old projector. Whatever it
was, it required the high speed blanking capabilities of the AOM.
 
It's looks to be incomplete head. It is missing the tube. The tube pumps this module from outside. The thick red line leaving the power supply is the positive HV line. The negative I don't see, and the others go to the PCB in the corner. Which is probably the controller. I can't see too well in the pics, but follow the wiring and mirror paths and you'll find an answer.

Hahaha. I think you'll find a HeNe hiding underneath all that meet shetal.

AOM RF input on the upper right and what appears to be a DC input on the left, Both F

The third connector is a mini-F, for what I can't tell. The wires for that appear to be heading down
underneath to where the bute is. Got any pix from the other side?

I think we have reached the edge of "Pons asinorum (Latin for "bridge of fools").
No more guessing on my part.

Very cool! So, these would be used for things like measuring earthquake displacement over time and large distance, or something like that?
