ABSTRACT:
A laser system uses a nonlinear crystal ring resonator to produce Type II nonlinear second harmonic generated light. The reflective surfaces of the resonator are oriented to form two closed beam paths for the two fundamental frequency light beams having different orthogonal polarization. The two beam paths overlap along one segment which is parallel to an axis of the nonlinear crystal. Second harmonic generated light is produced along this segment of the beam paths.
