Abstract
A laser system uses a nonlinear ring resonator to produce Type-II nonlinear second harmonic generated light. The reflective surfaces of the resonator are all symmetrical with respect to the crystal axes. This allows orthogonally polarized light to be resonated along the same beampath in the resonator without experiencing bireflection.
