Abstract
A proximity detector for the probe of a beam delivery apparatus of a laser system includes a probe having a face for confronting a target surface to be struck by the laser beam; means for directing a gauging light to the target surface; means for sensing the gauging light returning from the target surface to the probe; and means responsive to the means for sensing for generating a control signal representative of the position of the probe relative to the surface to enable the laser system to fire.
