I have an opportunity to buy a Lexel Model 95 ion laser - what can I do with it?

Holography just requires high stability of frequency and long coherence length. Single mode HeNes are used because they typically have coherence lengths around 100 meters and they are plentiful and efficient.

Thanks, but many kinds of lasers are used now and I need single argon line about 2W which is what this one is supposed to do in several wavelengths as single lines. I can't say I wouldn't like to play with all those multiline watts but I mostly want one at a time. Just thought someone might have some experience making a hologram with one of these beasts. Thanks!

I got about 1.7 watts of 514nm at full current, and that was with a hot tube. The other lines produce less power, some significantly less.
