Yes, the infrared ones can be a bit dangerous. I worked for 25 years in the Telstra Research Labs and we had a carbon dioxide (infrared laser) with an output of 600W, no I didn't forget the "m", (peak pulse power was about 1.2kW, thats 1,200,000mW) and that little sucker could cut through 3mm steel like butter, perspex was even more fun! We even used it at times for "real" work! I still have my name burnt into a piece of wood with it. I don't think it would be much use for pointing out stars though, being invisible. But if a plane flew overhead, it would probably just got straight through and cut the wing off
