You can make you own high powered N2 UV laser for under $25. Check out Sam Goldwasser's page.

Laser output: The home-built N2 laser operates at 337.1 nm producing pulses of ultra-violet radiation in the UVA region of the electromagnetic spectrum. While its peak output may be 100 kW or more, the pulse duration is only a few nanoseconds at most. The pulse repetition rate (for the SciAm design, at least) may be anywhere from one pulse every few seconds (using the DC powered HV inverter) to several (maybe as much as 120) per second (using a neon sign transformer based power supply). A 5 ns 100 kW pulse has an energy of .5 mJ which may not sound like a lot but is still a potential hazard. At a pulse rate of 120 pps, the average power is 60 mW which IS a significant amount of UV light. Since the N2 laser doesn't produce a particularly well collimated beam, it won't focus to a very small intense spot. Thus, I doubt that it will be possible to use this laser to burn things.
