You can probably do phased arrays. (It might already be a phased array.)

Pretty sure phased array LASERs are not yet a thing.

		I was not sure, but they are! https://cga.anu.edu.au/research/activities/laser-beam-steeri... https://www.darpa.mil/research/programs/excalibur I guess in some ways even the fancy multi diode fiber lasers are phased arrays, just with the single goal of higher output power.

		Lasers are coherent emitters; you can definitely make interference patterns with them, so I don't see why LASER MIMO wouldn't be possible, in theory.

		Yeah but this is research, if they're to come up somewhere, where else would it be?
