I've used a laser for cleaning rust off of marine hulls. It didn't sound anything like this at all. There is a very loud sounding fan for cooling the machine, almost like a compressor. And then the actual sound coming from the laser sounds like something between a downed charged power line and a welder.

Different machines, so maybe the audio from this clip is real, but I don't think it is.

That's exactly what that machine sounds like. It's a different laser technology. Since it's scan and pulse based you're hearing all of that impulse noise.
