  • Solid state laser
    Publication number: 20020122455
    Abstract: The invention is directed to a compact optically side-pumped solid-state laser with an optimized overlap between the mode of the laser beam propagating in the laser material and the pump beam. Using a common pump volume, the compact solid-state laser can simultaneously emit laser beams at different wavelengths. The laser can be combined with nonlinear optical elements to provide a RGB three color laser architecture suitable for color projection display applications.
