Multimode pumping of optical parametric oscillators

Cooperative oscillation of nondegenerate transverse modes in an optical system: multimode operation in parametric oscillators.

We show experimentally that parametric interaction can induce a cooperative oscillation of non-simultaneously resonant transverse modes in an optical parametric oscillator. More generally, this effect is expected to occur in any spatially extended system subjected to boundary conditions where nonlinear wave mixing of two nonresonant spatial modes can generate a resonant oscillation.

Continuous-wave Optical Parametric Oscillators

Since the publication of an earlier review on optical parametric oscillators (OPOs) in 2000,1 there has been remarkable progress in the technological development and applications of OPO devices. Once considered an impractical approach for the generation of coherent radiation, OPOs have now been finally transformed into truly viable, state-of-the-art light sources capable of accessing difficult ...

Selected Recent Advances in Optical Parametric Oscillators

Optical parametric oscillators and precision optical frequency measurements

We report experimental results of frequency tuning, stabilization, and beat-note phase noise measurements of a type-II phase-matched potassium titanyl phosphate (KTP) doubly resonant optical parametric oscillator (OPO). Three types of OPO cavity design were constructed and experimented for their mechanical stability and frequency tunability. Four tuning elements were employed in our 2-element a...
