I watched a video yesterday about the laser range finder on a tank. The interesting thing is that at long enough ranges, the laser expands into a cone that may be bigger than the target and give inaccurate readings.
Anyway, I look forward to this totally real and feasible technology.

Exactly, a laser pointer, while casting a millimeter-sized dot of light at short distances, its light easily gets meter-sized when they reach flight cruise heights, shining airplane’s cabins and interfering with the pilot’s vision. However, as by inverse square law, the power is distributed across the beam.

So you’re saying a space orbiting death ray will cast an area large enough to generate solar powered eh? HEY ELON!

On the contrary.

So a really bug death ray? Perhaps some sort of doomsday device?
