“Any atmospheric pressure linear spark with a field greater than about 10kV/cm will show stimulated emission from nitrogen.”
This type of laser design is a well-known curiosity. It is not useful or reliable, and always winds up on a shelf somewhere, or in the trash.
- blincoln 6y agoI'm really happy it was posted here, since I've never heard of this effect. Do you have some further reading on the "not useful or reliable" aspect? This site, for example, lists multiple applications for them: http://technology.niagarac.on.ca/people/mcsele/lasers/LasersN2.htm http://technology.niagarac.on.ca/people/mcsele/lasers/Lasers...
- blincoln 6y agoIt's especially interesting to me because (as the article points out), it doesn't require any really exotic equipment or skills to build one. I'm a little surprised no one built one long before helium-neon lasers.
