Abstract

Optical parametric oscillators (OPOs) represent a versatile class of coherent light sources that can provide widely tunable radiation in spectral regions inaccessible to conventional lasers. The advent of birefringent and quasiphase-matched (QPM) nonlinear crystals such as BBO, LBO, PPLN and PPKTP, combined with the development of new laser sources based on solid-state, semiconductor, and fiber laser technologies, have led to the practical realisation of OPO devices with previously unattainable performance capabilities. Using novel resonator designs and pumping concepts based on intracavity, pump-resonant, and twin-cavity concepts, stable single-frequency operation of CW OPOs at practical powers from a few mW to greater than 1 W and mode-hop-free tuning over 50 GHz has been demonstrated.
