  • Single-frequency laser of improved amplitude stability
    Patent number: 5031182
    Abstract: A solid-state laser of improved amplitude stability is obtained by substantially eliminating spatial hole burning in the lasant material and maintaining the optical cavity of the laser at a temperature which results in substantially noise-free generation of output radiation.
    Type: Grant
    Filed: October 2, 1989
    Date of Patent: July 9, 1991
    Assignee: Amoco Corporation
    Inventors: Douglas W. Anthon, Pedram Akhavan-Leilabady
  • Simultaneous generation of laser radiation at two different frequencies
    Patent number: 4956843
    Abstract: The output of a single semiconductor light source is used to optically pump two solid state lasers which are arranged in series and produce laser radiation at two different frequencies. Single longitudinal and single transverse mode operation can be achieved in both lasers.
