  • Intracavity modulated pulsed laser and methods of using the same
    Patent number: 5832013
    Abstract: An intracavity modulated pulsed laser and methods of using the same. In one preferred form, an intracavity modulated pulsed laser comprises an amplification medium, a pulsed pumping source, a beam modulator, and two mirrors, one totally reflective and one partially reflective for generating at least one laser output burst comprising a plurality of sub-pulses having variably controllable peak powers. In another preferred form, a non-linear crystal is utilized to double the frequency of each laser output burst. In still another preferred form, a fluorescence feedback control circuit is utilized to control the beam modulator.
    Type: Grant
    Filed: December 17, 1996
    Date of Patent: November 3, 1998
    Assignee: American Dental Technologies, Inc.
    Inventors: Michael J. Yessik, Richard G. Thompson
