I haven’t really been paying much attention, but last I looked, lasers ran into sustained-rate-of-fire issues, which is one of the things that you’d want something like this to be able to do.
They’re nice in that they can counter very-fast-moving missiles – can’t outrun light or the laser’s panning speed – but I don’t know if a powerful laser is necessarily a cost-effective way to deal with a large number of inexpensive drones.
Do those maintain the kind of beam coherency required for long-range use?
I think that the weaponized lasers I’ve seen in actual military use, like the AN/SEQ-3, are pulse lasers. I don’t know why that is the case; if I had to guess, it might be necessary to avoid some forms of defenses, like producing so much thermal expansion so quickly that it tears apart ablative armor or prevents the target from rotating or rotating some form of shield to change the point exposed to the laser. I don’t really follow laser technology, though. Are these capable of pulsed output?

There are cheap continuous operation 2 kW fiber lasers for material processing which could be enough for the flimsier slower drones.
