I have a small Helium-Neon laser that I would like to attempt to
use for voice communication and desire a little help from those
of you who have done this. Is it possible to modulate the laser
simply by modulating the input power supply? In this case tube is
powered by a 12 volt DC/DC converter. If not then what other
"simple" ways of modulating can be used?
What about detectors? I would like to be able to detect the beam
from a distance of several miles. What kind of detectors work well
in this application? Is it possble with a 4 mWatt laser? Can a lens
help if the intensity is too weak?
Any and all help appreciated, thanks much.
