TL;DR: In this paper, the phase conjugation of a laser beam aberrated by a thin random-phase screen was investigated when the wave front is incompletely sampled by the PCM.
Abstract: We investigate phase conjugation of a laser beam aberrated by a thin random-phase screen when the wave front is incompletely sampled by the phase conjugate mirror (PCM). We derive expressions for the average intensity after a double pass of the phase screen both when the PCM is aperture limited and when it is limited by its number of spatial modes.

TL;DR: In this article, an efficient numerical 3D model of transient stimulated Brillouin scattering (SBS) was presented. But the model was used to examine the effects of transient phenomena on the efficiency of phase conjugation by SBS and the mode structure of the Stokes and pump pulse inside the SBS cell.
Abstract: An efficient numerical 3-D model of transient stimulated Brillouin scattering (SBS) is reported. The model is used to examine the effects of transient phenomena on the efficiency of phase conjugation by SBS and the mode structure of the Stokes and pump pulse inside the SBS cell. The effect of parameters such as phonon lifetime, input pulse shape and input energy on the transient fidelity of SBS is investigated. A new transient phenomenon which causes SBS fidelity degradation at high focal intensity (short Rayleigh range) is examined.

TL;DR: Data is presented showing nonlinear resonantly enhanced photorefractive response at high modulation depths in InP:Fe with large-signal effects as well as linear absorption on the self-pumped phase-conjugate mirror.
Abstract: We present data showing nonlinear resonantly enhanced photorefractive response at high modulation depths in InP:Fe. A simple empirical model is used to describe the behavior. Next the impact of these large-signal effects, as well as linear absorption, on the self-pumped phase-conjugate mirror is examined. Finally we compare predicted performance to actual measurements of a ring self-pumped phase-conjugate mirror using InP. The performance of the double-pumped phase-conjugate mirror is also examined experimentally and compared with the performance of the ring mirror.

TL;DR: In this article, the operator form of the wave equation is employed to indicate the symmetry properties of the diffracted field under coherent and partially coherent illumination, which are of interest in holography, phase conjugation, and for automatic focusing.
Abstract: The operator form of the solution for the wave equation is employed to indicate the symmetry properties of the diffracted field under coherent and partially coherent illumination. Such symmetries are of interest in holography, phase conjugation, and for automatic focusing.

TL;DR: In this article, a ring interferometer was used to align the optical alignment of matching the wavefront measurement and shaping. But the alignment was not solved by optical phase conjugation.
Abstract: We propose and experimentally demonstrate digital optical phase conjugation implementation for delivering two-dimensional images through turbid media Employing a ring interferometer, the optical alignment of matching the wavefront measurement and shaping has effectively been solved
