摘　　要：理论分析和实验研究了非相干光照射下Ce∶KNSBN晶体中的两波耦合 ,发现非相干光在很大范围内可有效地控制晶体中的两波耦合效应。实验结果和理论分析趋势相一致。We have analysed the results of the photorefractive two-wave mixing in Ce∶KNSBN controlled by an incoherent beam and performed experiment. Results show that the incoherent beam can effectively control the photorefractive two-wave coupling gain in a large range.The experimental results agree with the theory well.
