Study of the Response Time of Two-beam Coupling in photorefractive Crystals
Considering the change of the grating modulation index, a united analytic formula of the response time for two-beam coupling is obtained by solving the dynamic equation of two-beam coupling. It involves paratmeters of crystals, incident intensity, full incident angle and signal-pump ratio. The experimental resultS using Ce:KNSBN crystal are in good agreement with the theory qualitatively.
