Here's one of my 1mW GreeNes

That almost seems to be giving a class on exotic atomic shell desnsities in the process
Then again, getting the green line to lase on a HeNe is much more difficult that getting the 'default' 633 nm line.
I'm not sure they even sell those kits anymore with the populatiry of laser diodes, but somehow i'd like to have one of them just to see if can still make it work, despite the rather low ouput power (1 mW for the win on that).
Ther wasn't a diode when Metrologic build the pointer. I bought their "Build a Laser kit" back in 88' a red 1/2Mw and still have it today. The green laser pointer was around 800-900 bucks at the time I bought my kit. I can posts some pictures later if you want.

wow 1988
that is ancient
i did not know people were already buying lasers back then :wtf:
Gass lasers have been around since the early 60's when they were invented. Kids today. LOL
