  • Non-confocal unstable laser resonator and outcoupler
    Patent number: 5943358
    Abstract: An unstable laser resonator geometry with a gradient reflectivity mirror M) and external lens, or a gradient reflectivity mirror-lens (GRML), achieving a vast improvement in the intrinsic divergence and brightness of the output laser beam.
    Type: Grant
    Filed: July 9, 1997
    Date of Patent: August 24, 1999
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Toomas H. Allik, Suresh Chandra, J. Andrew Hutchinson
  • Solid-state dye laser utilizing multiple dyes in single host
    Patent number: 5805623
    Abstract: A solid-state dye laser and technique for achieving multiple output wavelength laser emission from a single solid-state dye laser media containing multiple dyes without tuning elements. When the multiple dyes within the single solid-state host are excited with a single wavelength pump source to lase, there results simultaneous multi-spectral output proportional to dye concentration ratios.
