Yes but again, air or any non linear optical material is made of a bunch of
fermions, bosons like light photons just don't react with other bosons worth
a damn. And we were talking about communicating over interstellar space
after all, a pretty good vacuum.

The creation of electron- anti electron and even proton- anti proton pairs has
been observed, but not from radio, light, or even X rays photons, you need
Gamma rays.
