I have considered attempting to use a DC arc welder to power a carbon arc lamp as a pump. Anyone else attempted this?
(From: Heath Edwards (heathe@citi.w1.com).) I use my Lincoln AC arc welder with a twin-carbon arc torch. The carbons are 3/8″ diameter and copper plated for strength. I wouldn’t recommend this type of torch because the carbons burn down fairly rapid. Just having done some light brazing with the torch the rods have shortened several inches. Which means you would need to have an automatic rod adjuster. Now if you used larger diameter rods, they might run longer. But they’ll require more current. The light intensity is certainly high! You HAVE to wear welding goggles with a dark lens of #8 or better. (From: Mike Poulton (tjpoulton@aol.com).) I would like to build a dye laser for use in light shows and classroom demonstrations. I have built several lasers, but never completely from scratch. My question is about an interesting phenomenon which was referred to in a small piece of literature about dye lasers. It seemed to imply that if you direct the beam of a nitrogen laser through a chamber
