【Abstract】 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.更多还原
