Instability of Spatial Subharmonic under Hologram Recording in a Photorefractive Crystal,

Abstract

Wave mixing experiments in photorefractive crystals (PRC) have resulted in the observation of large number of interesting phenomena. Communications about spatial subharmonic generation were published. Subharmonic gratings with a wave vector q/n (n - integer) have been occuring during the illumination PRC Bi12SiO by moving interference pattern with a wave vector q. Authors of suggested the mechanism of generation of subharmonic at the expense of noise component amplification in the field of two pump waves.
