It could be that the radiating efficiency of the hardware is only 60%, ie lost to heat or in some other phenomena in the circuitry.
I'd imagine they'd never get approved blasting 400w per kW erratically.

We are using a strictly point to point collimated beam that is expected to meet nothing but clear air. It shuts down if/when any transient object is about to enter the beam path.
Also, don't forget that the important figure you should be looking at is power density rather than total power
You also claimed it's unaffected by rain.
Which is it?
Rain will trip the laser screen, as will fog.
Ergo, this will only work in clear air. Rain and fog will shut it down.
