  • Method and system for compact efficient laser architecture
    Patent number: 9136668
    Abstract: A laser amplifier module having an enclosure includes an input window, a mirror optically coupled to the input window and disposed in a first plane, and a first amplifier head disposed along an optical amplification path adjacent a first end of the enclosure. The laser amplifier module also includes a second amplifier head disposed along the optical amplification path adjacent a second end of the enclosure and a cavity mirror disposed along the optical amplification path.
    Type: Grant

  • Method and system for edge cladding of laser gain media
    Patent number: 8682125
    Abstract: A gain medium operable to amplify light at a gain wavelength and having reduced transverse ASE includes an input surface and an output surface opposing the input surface. The gain medium also includes a central region including gain material and extending between the input surface and the output surface along a longitudinal optical axis of the gain medium. The gain medium further includes an edge cladding region surrounding the central region and extending between the input surface and the output surface along the longitudinal optical axis of the gain medium. The edge cladding region includes the gain material and a dopant operable to absorb light at the gain wavelength.

  • Method and System for Mitigation of Particulate Inclusions in Optical Materials
    Publication number: 20120180527
    Abstract: A method of fabricating an optical material includes providing input materials having a material softening temperature, melting the input materials, and flowing the melted input materials into a laser inclusion mitigation system. The melted input materials comprise one or more inclusions. The method also includes irradiating the input materials using a laser beam, fragmenting the one or more inclusions in response to the irradiating, and reducing a temperature of the input materials to less than the material softening temperature. The method further includes forming an optical material and annealing the optical material.
