If the lasers can excite the moisture molecules around ear area for audio ......couldn't we assume they can modulate at supersonic too?

You wouldn't want the beam to be visible....so maybe black light? Might disturb wildlife and give you away. What about IR? At long distance and high levels, one might feel heat with that audio. An IR beam might be a flare to outside detection.

How low in frequency can our lasers go?

Some people just can't hear the voices. I'm on a party line.

Can we detect the modulation on a laser, by passing another laser thru it?
