Paper Abstract

We study the cross-talk between the competing holographic gratings in photorefractive cubic crystal Bi12SiO20. The cross-talk technique applies to measure a reduction factor which distinctly appears at low spatial frequency free electron distribution in diffusion regime under conditions so that direct observation of photorefractive gratings can not be performed. We suggest a hypothesis for the reduction factor of the carriers distribution with respect to light modulation is a long-distance photoelectron migration related to a high initial kinetic energy of the free carriers.
