Studies of Optical-Beam Phase-Conjugation by Nonlinear Refraction.

Abstract

We demonstrated the first cw phase-conjugating mirror with gain, and made a self-oscillating resonator which emitted a diffraction-limited optical beam while severe phase aberration was present in the resonator. We demonstrated storable and erasable phase-conjugate images in the nanosecond regime by a one-photon photorefractive process. We achieved the first demonstration of a wide angle ( approx. 45 deg.) narrowband approx. 1/10 cm) optical filter using phase conjugation. We achieved the first demonstration of full vector-wave phase-conjugation by which an image was restored after double-passing a birefringent phase aberrator. We demonstrated edge-enhancement of an optical phase-conjugate image in real time. Studies of resonant nonlinear refraction and phase conjugation in sodium vapor continued. (Author)
