The inverse square law only applies to a point source radiating uniformly in all directions.

Laser and microwave beams, while they do suffer from losses over distance, aren't anywhere near that bad.

The inverse square law still applies to directional transmitters and optical transmitters. It's just that their transmit gain is much much higher.
