Why not?

Here's a video of a 500 W laser cutting a set of mirrors: https://www.youtube.com/watch?v=p-VlVmBZGI4

From a few inches away from the focusing lens, yeah.

If the ship-mounted laser is powerful enough to take down a drone, it's already delivering way, way more power at a distance than the cutter shown in the video does at a few inches.

Mostly because mirrors aren't perfect.

Let's say if a mirror can reflect 99% of the light that hits it, and we shot it with 1kw laser. That means 100w is still heating the mirror and it might melt or shatter it.

Still, that would require a laser blast 100x as powerful to take down the drone. Also: what would that do to the effective range of the weapon?

Plus, depending on how much control the attacking drone has, that's also 99% of the beam being deflected back at the ship with the laser.

No. It’s 10W. Not 100W.

Ofc, it's just an example. I realized later I made mistake, till then edit window was gone.
