Abstract

Highly efficient holographic enhancement of weak laser beam was experimentally observed in a single crystal photo-refractive fiber of Bi₁₂TiO₂₀ at (lambda) equals 632.8 nm under applied external alternative electric field. Experimental investigation of phase conjugation of two mutually incoherent laser beams in the same fiber is presented. Phase conjugate wave reflectivity close to 7% and with a response time of a few seconds was measured at (lambda) equals 632.8 nm with 24 mW power He-Ne laser.
