Colored HeNe

[Cyparagon]

Why haven't I seen any multiline HeNes? I've seen many different wavelengths: green, yellow, red, IR... but never all in one tube (like argon). Is it a gas proportion issue, is it an optic issue, or is there just no demand for such a laser?

Tunable HeNes are available.. Check out Research Electro-Optics (Formerly PMS).  They are expensive and the gain is lousy.  The lines available are: 543.5, 594.1, 604.6, 611.9, and 632.8 nm.  The ideal bore to mode ratio is different for the different lines so no line is really optimized.

What I mean is a multiline HeNe - either 2 or all the HeNe lines at once in one beam.

Why did they change their name? :

I think PMS Electro-Optics was originally a division of Particle Measuring Systems and then spun off into an independent company (Research Electro Optics) in the mid-90's.

there was a joke in there...

All HeNe lines at once? Don't got nuff gain I suppose

 

[laserrod]

I concor.
Very lousy gain. One line robs the others. I would try to segment the plasma and resonators so the output would be all the lines from right to left. Not combined.
Rectangular plasma bore.

Why did they even choose PMS in the first place?? :
