    摘要: 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.
