Abstract
The distribution of two-wave mixing coefficient as a function of pump beam incidence has been measured for the Bi12TiO20 photorefractive fib re. Double phase-conjugate mirror with its conversion efficiency highe r than 5% has been recorded in a wide range of the pumps incidence ang les at lambda = 632.8 nm for a 2 x 3 mW input light power. Self-pumped phase-conjugate minor with efficiency of 3% was obtained by using int ernal reflections of fanning beam inside the fibre.
