OPTICAL-PARAMETRIC OSCILLATION WITH INTRACAVITY 2ND-HARMONIC GENERATION

We consider combining frequency down-conversion with frequency up-conv ersion in the same cavity as a means of producing tunable up-converted radiation. Specifically, we consider a singly resonant optical parame tric oscillator (OPO) containing an intracavity second-harmonic genera tor (SHG) for doubling the OPO signal frequency. We determine the stab le steady states that completely deplete the incident pump radiation. Phase mismatch in the SHG process is considered. An example of convert ing 532 nm radiation to 365 nm radiation is discussed; power conversio n efficiency as high as 63% is predicted.
