At play in what, exactly? Are you still stuck on trying to figure out how they are using lasers to make people hear things...? Because that's not how they do it... Modulating an auditory signal onto an ultrasonic carrier wave is the most basic way to pull off Voice-to-Skull, and has been since they figured it out more than a decade before I was born.....
Just happened to read something where "light waves" have no mass, but do have momentum.... Perhaps that is the mechanism at play here?
