It would not be very hard to rig laser communications. Just have a
laser and hook it up to a computer which turns it on an off very
rapidly according to the data that is being sent, and have a
photosensor sensitive to the particular frequency that the laser is
using, which sends the data it gets to an A/D converter, which in turn
sends it to another computer. The computer then interprets anything
in a particular minute unit of time over a particular threshold as
being a 1 and everything else is a 0. Mirrors are used to direct the
laser beam, in case there is no direct line of sight between the laser
and the photosensor.
