ABSTRACT:
Apparatus for multiplexing a coherent high power CW laser beam has a mirror mounted on a galvanometer to interrupt the laser beam and another mirror mounted on another galvanometer to deflect the laser beam to a selected pair of optical fibers. The other mirror is moved only when the laser beam is interrupted to avoid fiber damage. Yet another mirror mounted on a galvanometer can be used to provide a greater number of addressable fibers. A method of multiplexing comprises interrupting a laser beam, deflecting it, changing its direction only when interrupted, focussing it, and transmitting it through the optical fibers.
