When I saw those photo's on ebay, I thought that was the front with a sticker covering the aperture.

I have a similar looking PM10 head, just a thicker housing
and the label is on the rear. Maybe these labels are on the
front.
I asked the seller to send some more pics of the OTHER side.


[EDIT]

Just got a pic of the front. The aperture seems smaller than
the diameter of the BNC connector.

I've bought from that seller several times, they don't understand laser equipment well, but get some from time to time. Always have been good to work with and willing to work deals, if I needed time to pay.

The part number suggests it's 635nm at the bottom of this page >>>> Beam Splitter Glass Home Depot | Science Lab Equipment

Thanks RCB, appreciate your help. I was looking for 1064nm cubes.

Here's something which might be of interest to someone, occasionally I see posts from individuals looking for 5mw or less, these are 3 mw red laser diodes, 15 each as a lot:

Part of a dye laser?

I doubt it. A dye laser wouldn't need the dye routed to that many different elements (in the head at least). The tubing looks like it's for coolant, though why every element of the assembly would need active cooling is beyond me.

Without actually looking down the bore, my best guess is some sort of spatial filter or optical train for a very high powered laser.

EDIT: Also, that model number might only be for the 4-reflector assembly on the end, rather than the entire unit.

I meant for cooling the optics for a dye laser. You are right way too many cooling hoses just for dye.

JDS Uniphase 2214-40MLA 458-515nm Argon-Ion Laser Head +2114B-40MLA Power Supply | eBay

3 available at about $340 each ($80 shipping)... but they accept offers... not bad for a multiline. You just need a fan.

AND a power supply control interface.

$400 for an untested ion laser missing parts would have been a deal 10 years ago, but that's pretty high these days.

Also note the 240V power supply. Most people don't know how to get 240V (or don't care to learn). It may or may not be reconfigurable internally for 120V, but again, that's a project most people don't want to undertake.
