A rifle has a muzzle energy of a couple kilojoules. So you're looking at lasers in the kW power range. I doubt that you could do comparable damage even if you could deliver comparable energy. Flesh doesn't conduct heat terribly well and vaporizing a centimeter of skin is not very lethal.

Sure, but who hasn't thought of turning their enemies into zebras?

Just throw an Arduino, some servo motors, a camera and some ML on it and you can keep the squirrels off your bird feeder.

edit: if it's not obvious this is a joke
