Tattoo removal tends to use ~1MW pulsed lasers (yes, megawatt). The pulse is extremely short (nanoseconds), but at that power/instant-brightness it's enough to fry sensitive imaging electronics. Can also do fun things like blast holes through CDs. I'd learned about the topic the other day here ("plays" with a cheap tattoo removal kit off the web): https://youtu.be/-BeTq99LqUo https://youtu.be/-BeTq99LqUo
