基于“桶中能量法”的相位共轭保真度测量研究
-
摘要: 给出了基于“桶中能量法”的相位共轭保真度测量原理、方法与结果。通过对适当大小的空间滤波针孔能量透过率的直接测量可以得到相位共轭保真度并简单实现系数 标定, 给出了针孔大小的选择原则、系数标定方法和共轭保真度的计算公式以及单池受激 布里渊散射相位共轭镜在几种条件下的实验结果, 指明了这种方法的重要性与不足之处。Abstract: A principle, method and result of phase conjugation fidelity measurement based on “energy in the bucket”is psented. It is easy to obtain conjugation fidelity and realize the system calibration by measuring directly energy transmission ratio of spatial filter's pinhole with proper diameter. Choice criteria of pinhole diameter, coefficient calibration method, calculation formula of conjugation fidelity and experimemtal result of stimulated Brillouim scattering (SBS) phase conjugation mirror (PCM) with single cell under several kinds of situations have been provided. Finally, we point out its practical importance and defection．
