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 qn 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.
