Parametric coherent oscillation with feedback via an orthogonally polarized wave

Abstract

Coherent light amplification with photorefractive crystals may be a consequence of several frequency degenerate (or nearly degenerate) processes of nonlinear wave mixing : It appears for two- beam coupling in the crystals with diffusion-driven charge transport [1] or transport via circular photovoltaic currents [2].

Anisotropic Four-Wave Mixing in Optical Waveguides

Photorefractive crystals like LiNbO3, KNbO3 or BaTiO3 are suitable media for frequency degenerate two- and four-wave mixing allowing for amplification and phase conjugation of coherent light beams [1, 2].

Critical Enhancement of Photorefractive Beam Coupling

Evgeniy V. Podivilov, Boris I. Sturman, H. C. Pedersen +1 more

We show that a hybridization of the optical and material nonlinearities takes place near the threshold of the subharmonic generation in photorefractive crystals. It results in a critical (with a singularity) enhancement of the rate of spatial amplification of light waves and leads to a variety of new optical critical phenomena.

Coherent-beam amplification and polarization switching in a birefringent medium-photorefractive crystal

I. C. Khoo, Y. Liang, Haorong Li

A recent theory of polarization switching and beam amplification effect in Kerr-like media is extended to birefringent photorefractive crystals. In this class of material, the birefringence allows a new mechanism for coherent nonlinear mixing effects among the extraordinary and ordinary waves, leading to amplification and polarization switching effects. Analytic solutions of the parametric equations governing these interacting waves are solved for both the phase-matched and phase-mismatched geometries. The authors also present an experimental confirmation of the predicted polarization switching effect.>

Coherent optical gain of multistage two-wave mixing in photorefractive crystals

Jinsong Liu, Jianyong Xiang, Keqing Lu

We derive the intensity and phase formulas of the two-, three-, and n-stage codirectional parallel-polarization degenerate two-wave mixing in photorefractive media. These formulas are valid for both the saturation and intermediate regime and can be used in investigating the problem of increasing the coherent optical gain by the multistage two- wave mixing technique.

Self-oscillation in a photorefractive phase-conjugate mirror with linear absorption II Anisotropic four-wave mixing

Nitin C. Kothari

The effects of linear absorption on the degenerate and nondegenerate self-oscillation of a photorefractive phase-conjugate mirror under condition of anisotropic four-wave mixing are considered. The phase conjugation results from nonlinear mixing of two strong undepleted orthogonally polarized counterpropagating pump waves with a probe wave. We consider two types of situation for orthogonally polarized pump beams corresponding to two crystal families: one such as the Bi12SiO20 crystal family (sillenite family) and the other such as the BaTiO3 and strontium barium niobate crystal family. In both of these crystal families the degenerate and nondegenerate self-oscillations are shown to occur in the presence of linear absorption, which tends to increase the value of the coupling coefficient required for self-oscillation. Numerical results are presented that exhibit various features of degenerate and nondegenerate self-oscillation in both crystal families for different values of the phase ϕb of the backward grating.
