Abstract
A diode laser pumps a laser crystal in a known manner. A series of bypass mirrors selectively bypass the diode output beam around the laser crystal and directly out the same exit port as the pumped laser output beam. A hand held enclosure houses this dual laser head and supporting optics in a portable laser housing. Support electronics are optionally enclosed along with the applicator assembly and a battery. A transceiver to a host computer is included along with an optional exhaust and filter system.
Claims13
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 and
- wherein 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.
2 more elements
A hand held laser apparatus comprising:
- a laser head;
- a beam steering assembly used to steer a beam generated by the laser head;
- a power source used to power all system electrical elements;
- a system controller to accomplish all command and control functions of the system;
- a contact sensor to shut down the laser head when an object other than a workpiece enters a path of a beam from the laser head;
- and wherein the contact sensor further comprises a low-power laser and a distance sensor.
