Abstract
Photorefractive BaTiO3:Ce was used to combine coherently a signal beam and two amplified pump beams at lambda = 678 nm. The master laser bea m was split and then amplified in two semiconductor laser amplifiers T he amplifiers were made from quantum-well laser chips by use of antire flection coating. 40% of the power could be transferred to the signal beam without transferring the phase distortions of the pump beams.
