TL;DR: It is shown that phase-conjugate energy reflectivity of as much as 20,000% with a four-pass geometry in the longitudinally pumped polymer dye was obtained at 564 nm with degenerate four-wave mixing.
Abstract: We demonstrate the use of highly efficient degenerate four-wave mixing for phase conjugation with multipass geometries in a polymer laser dye saturable amplifier. Phase-conjugate energy reflectivity of as much as 20,000% with a four-pass geometry in the longitudinally pumped polymer dye was obtained at 564 nm.

TL;DR: In this paper, a phase modulator encodes phase conjugation information and compensates the amt. aberrations, by which a desired output beam may be synthesized.
Abstract: PROBLEM TO BE SOLVED: To provide a relatively high average power fiber laser using optical fibers having relatively less complication than that of known systems. SOLUTION: A phased array 30 of parallel fiber amplifiers is coupled to a common master oscillator 22. The respective fiber amplifiers are provided with independently regulatable optical phase modulators 26. A wave front sensor 38 for leading out a feedback signal for phase control is used. Arbitrary phase profile information is impressed to this phase modulator, by which a desired output beam may be synthesized. Then, the fiber amplifier array subjected to the phase control functions as a synthetic aperture signal transmitter at an optical frequency. This fiber amplifier array is combined with a beacon phase surface sensor for the beam propagation in the amt. air. The phase modulator encodes phase conjugation information and compensates the amt. aberrations.

TL;DR: In this paper, a two-cell scheme providing a phase conjugation of powerful short laser pulses is proposed to solve the problem of liquid purification from molecular and dispersive admixtures.
Abstract: The features of liquid purification from molecular and dispersive admixtures are studied. The analysis has revealed the processes (thermal effects, microparticles heating with a subsequent optical breakdown, stimulated Raman scattering) limiting pumping pulse energy. These effects complicate also a realization of a high quality phase conjugation at SBS. The data concerning physical properties of liquid tetrachlorides and freons are presented. The picture of a behavior of liquid under conditions of an optical breakdown is described. Some recommendations regarding a choice of nonlinear media are formulated. The two-cell scheme providing a phase conjugation of powerful short laser pulses is proposed.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.

TL;DR: The existence of geometry and pulse-length-dependent piezoelectric contributions to pulsed degenerate four-wave mixing is demonstrated experimentally in this article, where the effects must be taken into account when measuring third-order susceptibilities in noncentrosymmetric materials.
