Wave mixing in photorefractive crystals with stable solutions and instabilities
Two-wave and four-wave mixing in photorefractive media with saturable gain and saturable absorption is analyzed. Solutions to wave equations are found in terms of quadratures and implicitly given functions. Different models of saturation are compared. It is found that for weak couplings energy transfer between waves is less effective in the strong unsaturated regime as compared to the saturated...
متن کاملLaser Phase Noise Rejection by Two-wave Mixing Photorefractive Interferometry
INTERFEROMETRY M. Dubois 1 and T. E. Drake General Electric Global Research, Schenectady, NY, USA; Lockheed Martin Aeronautics Co., Fort Worth, TX, USA Abstract: Laser-ultrasound is a technique currently used for the ultrasonic inspection of composites during manufacturing of advanced jet fighters. This technique is based on a shortpulse laser to generate ultrasonic waves and a long-pulse laser...
متن کاملEnergy transfer in two-wave mixing quasi-degenerated in photorefractive crystals
Wave equations describing the quasi-degenerated two-beam coupling in the photorefractive crystals for high frequency gratings have been solved. In the case of the quasidegenerate two-beam coupling, equations depend upon the coupling coefficient, the response time of the medium, the input beams frequencies, the absorption coefficient and the input intensity ratio. The response time of the medium...
متن کاملContradirectional two-wave mixing with partially coherent waves in photorefractive crystals.
We investigate contradirectional two-wave mixing with partially coherent waves in photorefractive crystals in the nondepleted pump regime. Equations governing the propagation of the self-coherence function and the mutual-coherence function of the signal wave and the pump wave are derived and simulated numerically. Numerical solutions of these equations are in excellent agreement with the experi...
متن کاملTheory of self-frequency detuning of oscillations by wave mixing in photorefractive crystals.
Interesting experimental findings of self-frequencydetuning effects of phase-conjugate mirrors (PCM's) were reported recently. 1-3 A dye laser in conjunction with a passive (self-pumped) phase-conjugate mirror (PPCM) caused an unexplained self-frequency scanning of the laser.1' 2 Another system of a cavity formed by two PCM's also demonstrated a nondegenerate oscillation. 3 Recently4 we present...
