文摘Recently optical amplifiers with a gain factor of 4000 have been cons true ted using photorefractive BaTiO_(3) crystal and CW At+laser^(1,2).In this letter we report for the first time that a high-gain coherent CW image amplifier was constructed by using two-wave coupling in a BaTiO_(3) crystal,and a gain factor of 21400 has been achieved successfully.
