  • Multi-function intra-resonator loss modulator and method of operating same
    Patent number: 5197074
    Abstract: A laser system is provided with a multi-function intra-resonator loss modulator to generate laser output having selectable amplitude within a relatively wide amplitude range and selectable duration within a relatively wide duration range while preserving mode quality, waist position, and divergence of the laser output.
    Type: Grant

  • Method and apparatus for laser processing a target material to provide a uniformly smooth, continuous trim profile
    Patent number: 5057664
    Abstract: A diode-pumped laser system (10) incorporates a polarization state control device (12) that provides a trim profile (84) having minimal striations (64) on a target material (42). The striations run generally parallel to the polarization direction of laser output light beam (L) and are diminished whenever the polarization direction is parallel to the laser trimming direction. The striations are substantially eliminated by circularly or randomly polarizing the laser output light beam.
