Recommend a good fan for a small argon?

[MarioMaster]

Another question I had, is what determines the lasing lines in these heads? is it solely the HR and OC optics or is there some other mechanism?

Yeah it's mainly just the optics. My Omnichrome argon I sold to Drlava had a prism on the HR side to select the wavelength you wanted. But throwing multi-line optics on a single line argon may not work real well if the bore is small. (there's a bunch of info about this on Sam's FAQ)

I'm pretty sure the JDS Uniphase tubes have hard-sealed optics, just like the small Spectra-Physics tubes do. If so, then you can't swap the optics to get multi-line performance out of a single line tube.

Yup, they are hard sealed. I was just curious more than anything, I already have a few multilines and I really wanted a single line, I was just wondering how they did it. Another thing I was wondering, and I think I already know the answer to this one, but was there ever any multiline blue argons made? For example, only 457 475 and 488nm? That would be pretty neat!

yes,
I have a laser physics 250 mW 250-MBL, its in those argon dental curers you can get on ebay. blau-violet only.

you can get dichroic filters to seperate out just about any line your want, and highpass or low pass dichroics, ie a pass blue reflect green and do it ouside the laser, or just find a pcaom and do colro control till your hearts content :-)

In most non prism line selective lasers, the HR is multiline and the oC is wavelength selective. I've had folks hold a multiline HR in front of a single line 488 non prism tube and get green as a training demo.
