Paper Abstract

Studying Bi12TiO20 photorefractive fiber-like crystals we experimentally proved that fiber geometry has many advantages compared to the usual bulk samples. Double phase- conjugate mirror with its conversion efficiency up to 8% has been recorded in a wide range of the pump's incidence angles at lambda equals 632.8 nm for 3 mW input light power. Anomalous behavior of the fanning effect time response has been observed in Bi12TiO20 fiber-like samples: the higher external electric field we apply to the fiber the faster response time we get.
