Helium Neon Lasers

Here, three helium neon lasers are used. A 2mW green bare tube, a 2mW yellow, and a 1mW red. The room has been fogged.

Nice lasers!

Is the red one the oldest of the three?

@magx1

I think that the tube in the yellow is the oldest of the three. The green is brand new from a US supplier.

where did you get those? how much did they cost?

@TheNuclearWatermelon

All bought off the web. Ebay and private sellers on laser forums.

The green one is a 543.5nm Melles Griot (model LGR192), its output power is pretty low (1.4 to 2.5mW) but it takes like >12KV to get it working but still good to have one of these because HeNe's were earliest of lasers.

I love how green HeNe's still have red plasma, it just looks wrong.

@TheNuclearWatermelon you cant buy helium neon lasers anywhere, plus normal lasers are better
