ABSTRACT:
Nonlinear optical cavities comprising a single or multiple ring paths for use with diode lasers are presented. In one embodiment, the total internal reflection surface of a monolithic or composite cavity is fabricated into a plurality of nonparallel planes. In another embodiment, a composite cavity with either a single end piece or a plurality of end pieces bound to a nonlinear resonator crystal is used to generate either a single or multiple ring paths. In several of the embodiments, incident laser beams entering one end of the cavity follow the ring paths and transmit from the other end of the cavity as a plurality of second-harmonic beams with a pre-defined spatial layout.
