Walk-off and pattern selection in optical parametric oscillators.
The effect of walk-off in pattern selection in optical parametric oscillators is theoretically examined. We show that a dynamic mechanism also allows us to observe the formation of structures for positive signal detunings. In this regime the pattern that is generated is a periodic array of kinks that separate regions in which one of two stable steady states is alternately selected. This structu...
متن کاملOrder parameter description of walk-off effect on pattern selection in degenerate optical parametric oscillators
Degenerate optical parametric oscillators can exhibit both uniformly translating fronts and nonuniformly translating envelope fronts under the walk-off effect. The nonlinear dynamics near threshold is shown to be described by a real convective Swift-Hohenberg equation, which provides the main characteristics of the walk-off effect on pattern selection. The predictions of the selected wave vecto...
متن کاملTwin beams, nonlinearity, and walk-off in optical parametric oscillators
We study the quantum properties of the spatially tilted macroscopic signal beams in the transverse pattern formed in a degenerate optical parametric oscillator above threshold. We show that walk-off leads to an imbalance in the intensities and fluctuations of these beams when nonlinear multimode interactions are effective. Still, quantum correlations between the two beams are preserved, so that...
متن کاملContinuous-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 ...
