Probably miniaturized versions of CIWS / C-RAM or laser systems.

These small drones attack single people and small infantry groups as well as small vehicles up to heavy armor. With laser there is the issue of portability, especially power supply. Also cheap reflective coating requires very high power densities for a kill. Apart from detection and tracking which can use fused microphone array and camera array data the time to react is very short and it has to provide high density of fire on the cheap. I’ve seen some shotgun use with very limited effectivity. Ditto nets. Maybe antidrone swarms can work, but power limits loitering time. Swarm attacks can easily overwhelm protection.

It looks like a hard problem.

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.

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

Nah, lasers too big. It would be a simple birdshot shotgun. Its detection and aiming.

When they are high up, they can be hard to spot and hear.
But a pair of sensitive mic’s and a camera designed to look for them could easily be paired with some AR glasses.

somebody already put lasers on F35 and israelis are using ground-based lasers as a complement to iron dome

Yeah, have you seen the size of those? Those are chem lasers in order to get the wattage needed to destroy something.

Plus you need the electronics/mechanics to track the device perfectly to keep the laser on target in order for it to do damage.

All completely unnecessary to drop a small drone out of the sky.
