Let's see if I can design this. You have a carrier wave (light) modulated by kilowatt peaks. Those peaks must have their periods extended long enough to be felt by humans. Those square waves must also be modulated by a low frequency.
If I'm up a tree with this concept, tell me why.
In Vietnam war days I worked on an airborne laser target designator system. The beam was infrared from a YAG laser which emitted 10 nanosecond pulses at something like 10 megawatts power. It was expanded to about 2 inches in diameter near the emitter, and at that size it produced an audible snapping sound when striking dry grass. One afternoon we were adjusting the boresight from the back dock of our building when I saw a crow sitting on a utility pole crossbar. The devil made me do it; I zeroed the beam on the crow and gave him a burst, expecting some kind of spectacular response. The old boy didn't pay a bit of attention. I presume his feathers were reflective enough that no heating took place.
Moral: For every weapon, countermeasures can be devised.
