摘　　要：首次使用国产光折变晶体BaTiO_3利用两波耦合效应,成功地获得相干光CW图象(强度)放大。文中具体给出了放大率与泵浦功率,泵光与信号光比率,泵光与信号光相对晶体晶轴取回的依赖关系。The coherent CW image amplification has been realized successfully by using twowave coupling in a photorefractive crystal. BaTiO_8 grown in our own country for the first ime, The amplification factor is more than 4000, The dependences of the amplifieationt factor on the intensity of pump beam, the ratio of pump beam to signal beam, the directions of the pump beam and the signal beam with respect to the crystal axis have also been measured respectively.
