Abstract

A photorefractive phase-conjugate mirror with linear absorption is examined. An objective of this study is to identify possible effects of absorption on the self-oscillation conditions of the mirror and the properties of the excited conjugate wave. It has been found that self-oscillation is still possible in the presence of absorption. However, the coupling coefficient required for self-oscillation must increase in magnitude with increasing absorption coefficient to counteract the depressing effects of absorption. A consequence of self-oscillation in the presence of absorption is enhancement of the mirror reflectivity. A parametric study of the absorption-enhanced mirror is presented.

Additional information

The authors wish to acknowledge the contributions of Dai Sieh during the initial phase of this study. The work that he completed as part of his Master of Science thesis was an important element in our study of PCM reflectivity enhancement. The authors also acknowledge the assistance of Sahaid Rauf in carrying out some of the numerical solutions of Eq. 10, the governing equation of the self-oscillatory modes.
