ABSTRACT:
A system for directing successive beam pulses of a pulsed laser into different optical fibers, for transmission therethrough, is disclosed. The system comprises at least one lens, a plurality of optical fibers with the tips thereof positioned proximate a focal point of the lens, and at least one galvanometer driven mirror for directing a laser beam through the lens for focusing separately onto each fiber tip. The galvanometer, driven by computer generated position addresses, moves the mirror, between laser pulses, to predetermined positions each effective to direct the laser beam, through the lens, into one of the fiber tips for transmission via the fiber to a remote workstation location. In a first illustrated embodiment, a single mirror is mounted to direct the laser beam into fiber tips positioned substantially in the same plane and proximate the focal points of eight lenses. In a second illustrated embodiment, two mirrors are respectively mounted to scan the laser beam along "x" and "y" coordinate directions to direct the laser beam into fiber tip positioned proximate the respective focal points of four lenses.
