Sure, until someone says "hey can we stick this on a truck and use it against cars?" "Hey can we stick this on the belly of a plane and use it on a building?" "Hey what happens if we do a flash of this at protestors?"
Those kinds of tests have been done with lasers already.
This is a defensive application of lasers, like CIWS is a defensive application of guns.
We already have very cheap and effective ways to kill people.
Not so much when it comes to drone swarms.
My understand is it would be useless against a building, but you make a good point
It’s not going to do anything useful against cars, let alone buildings. It would blind people, and that would be bad, but it’s a very expensive way to hurt people. I think this one is for what it says it’s for.
Won't work very well. Such things need great stability.
And it's not like there's any need of a fancy weapon to do that. This exists to engage high speed targets. Just because you can use a GBU-28 to kill a gopher doesn't mean anyone ever will.
