Periodical Change

The photorefractive effect presents a periodical change of the refractive index of an optical environment under the influence of a coherent light. An interesting phenomenon which occurs at this effect is optical phase conjugation (PC). Photorefractive oscillators, that is photorefractive mirrors present important decides in photorefractive optics and their function is based on photorefractive effect. In these oscillators, a phase-conjugated light beam occurs. The basic characteristics of photorefractive oscillators, such as reflectivity, the existance of the oscillation threshold and the threshold of the coupling strength are explained by the so-called grating-action method. This is analysed on a ring oscillator, semilinear mirror and linear mirror.

The concept of optical wavefront reversing as a tool for phase aberration correction is reviewed. Presenting the fundamental and basic nature of the nonlinear interaction of light with matter leading to optical phase conjugation, a theoretical description of the photorefractive effect is given with a special emphasis on the gain of a coupling experiment and the speed of the photorefractive effect. Optical phase conjugation configurations, designs, and enhancement techniques are described and summarized comparing the possibilities and disadvantages regarding specific applications in the near infrared.
