I was once helping troubleshoot a UV laser in a lab. It was an IR Nd:YAG pulsed laser with two frequency doublers, and I think the rated output was something like 1 J. The measured UV output was essentially nil. We took off the second doubler and fired the laser at the side of a desktop computer we didn’t care about while wearing serious goggles. There was a little snap and the paint got replaced with a shiny metal spot. :) You do not want a laser like that anywhere near your eyes.
