摘要
基于钛酸铋晶体的吸收系数依赖于入射光强,考虑吸收栅对它的两波混合能量转移的影响,在某些近似条件下,推导出稳态两波耦合作用的表达式,与实验结果作了比较。测量了纯吸收栅的增益,给出结果。
The influence of absorption gratings on energy transfer of photorefractive two-wave mixing in Bi_(12)TiO_(20)is investigated. It is based on the dependence of the absorption coefficient in Bi_(12)TiO_(20)on the incident beam intensity. The expressions of energy transfer for two-wave mixing in Bi_(12)TiO_(20)are derived under certain condition and compared with the experimental results. The gains of the pure absorption gratings are meaured omd the results given.
