Sub-Diffraction Light Structures in Optical Parametric Oscillators
Previously, we have proposed a method of diffraction management in optical resonators with left-handed materials. This method is now applied to parametric oscillators. We show that it is possible to engineer the sign and strength of diffraction for either the pump or signal beam – not both. We study the influence of the altered diffraction on the periodic structures and phase solitons emerging ...
متن کاملGrowth dynamics of noise-sustained structures in nonlinear optical resonators.
The existence of macroscopic noise-sustained structures in nonlinear optics is theoretically predicted and numerically observed, in the regime of convective instability. The advection-like term, necessary to turn the instability to convective for the parameter region where advection overwhelms the growth, can stem from pump beam tilting or birefringence induced walk-off. The growth dynamics of ...
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 ...
