Simple DIY 337nm laser from air! (TEA nitrogen laser)

The TEA nitrogen laser was one of the very first DIY laser designs to be built by many hobbyists around the world. Scientific American published plans for a simple N2 laser in the 1970s, and since then there have been many other iterations by hobbyists. This is a very easy build that I recommend for anybody wanting to experiment with a UV laser beam!
