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!

I guess in some ways even the fancy multi diode fiber lasers are phased arrays, just with the single goal of higher output power.

Looks like these are in early development and nowhere near ready like this test was.

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?
