Unexpectedly fast response (35 ms) of beam fanning has been measured in a fiber-like photorefractive sample of Bi12TiO 20 (BTO) crystal. Nonlinear interaction between different directions of fanned beams is responsible for unusual angular distribution of the fanning emerged from the fiber that can be used for double phase-conjugate mirror (DPCM) recording with higher efficiency in a wider range of the pump's incidence than in a bulk sample. The DPCM with conversion efficiency up to 8% has been recorded in the BTO fiber at λ=632.8 nm for a 2×3 mW input light power. Practically, it means that no adjustment is needed to achieve an effective interaction of mutually incoherent beams, except introducing the pump beam into the fiber
