Helium Neon Lasers

[ignatei]

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.

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?

[seththeslayer1]

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

[billg519]

@TheNuclearWatermelon

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

The green HeNe is just plain awsome.

The yellow one continuously appears as reddish in your camera. What was the wavelenght of that again?

I like the clip with light on in the room. Me likes!
