Abstract:
A dual beam laser comprising:a diode laser emitting a diode output beam;a laser crystal assembly pumped by the diode beam, thereby emitting a pumped output beam from an enclosure;a bypass assembly to selectively divert the diode output beam away from the laser crystal assembly and out the enclosure andwherein the bypass assembly further comprises an input and an output bypass mirror and a first and a second fixed mirror, wherein in an active mode said input bypass mirror diverts the diode output beam 90.degree. away from the laser crystal assembly, the first fixed mirror diverts the beam parallel to the laser crystal assembly, the second fixed mirror diverts the beam 90.degree. toward the laser crystal assembly, and the output bypass mirror diverts the beam 90.degree. and parallel to the laser crystal assembly and out a common exit port as the pumped laser beam exits from; and wherein in a passive mode the mirrors allow the diode output beam to pump the laser crystal assembly.
