  • Method of laser surgery
    Patent number: 5970983
    Abstract: A method of laser surgery, comprising the steps of selecting lasers whose output radiation has appropriate extinction lengths in the tissue to be ablated, coagulated, and/or shrunk, and directing radiation from those lasers coaxially and substantially simultaneously at the tissue.
    Type: Grant
    Filed: July 31, 1997
    Date of Patent: October 26, 1999
    Assignee: ESC Medical Systems Ltd.
    Inventors: Ziv Karni, Michael Kreindel
  • High power infrared laser system
    Patent number: 5907574
    Abstract: A surgical laser system is provided with improvements to allow it to operate at higher power levels without beam divergence. The improvements include a beam expansion telescope in the optical path of the beam and modifications to the optical cavity and the lasing medium. The modifications include imposing a negative curvature on one or both ends of the rod, configuring the optical cavity as a positive-branch unstable resonator, and providing at least one intra-cavity shutter.
