Howdy there so you know about these HeNe lasers at all ? I recently was given a bunch of parts I hear actually make one of these lasers hear. I've got boxes of crap all in pieces and I was told everything is there plus some to make a really high quality laser. Only problem is ...I DONT KNOW JACK ABOUT LASERS ! But I totally want to build it just need a brain to pick lolWhat's the advantage of HeNe lasers these days? Is there anything they can do that diodes can't do better? Or is it just a matter of it being a cool tech? HeNe tubes definitely scream "laser" to me, much more than diodes.
