Of course there are no FCC regulations on IR radiation, because it is not
in the electromagnetic band normally considered to be "radio" frequencies.
The agency that monitors laser emissions and such is the B.R.H. (Bureau
of Radiological Health).  Their safety requirements are quite strict.
I used to work for a manufacturer of surgical lasers, and a significant
effort went toward ensuring they met B.R.H. standards.
