Abstract :
The light of a master laser and two semiconductor laser amplifiers was coupled coherently by means of a photorefractive InP:Fe crystal. A multibeam coupling arrangement, in which multiple pump beams interact with one signal beam simultaneously, was used. Energy-transfer efficiencies up to 48% were achieved
