title: High gain coherent amplification in thermally stabilized InP:Fe crystals under dc fields.
abstract: After recalling the principal results of the theory of two-wave mixing gain enhancement in photorefractive InP:Fe crystals under a dc field, we report on experiments performed with several samples manufactured at CNET. For the first time, we believe, a maximum gain of 11.4 cm(-1) has been obtained under an applied dc field of 10 kV/cm in a thermally stablized crystal (T = 290 K) at lambda = 1.06 microm. In spite of a decrease in the factor n(3)r(eff)/lambda high gains (Gamma >/= 5 cm(-1)) have been achieved at lambda = 1.32microm in thick crystals. These experimental results are in good agreement with theoretical predictions.
