关于倍频绿光问题的研究

摘要

采用双波片晶体的物理模型和Jones矩阵方法,得到了在连续多纵模腔内倍频激光器中压缩噪声的必要条件,推导出与Ⅱ类和Ⅰ类相位匹配方式相对应的消除和频效应的公式,并推广为往返Jones矩阵元所应满足的关系,以及相应的腔内本征矢.%An extended physical model on intracavity binary wave plates based on the Jones matrix formalism that gives the prerequisite for independently intracavity frequency doubling under CW multilongitudinal mode operation has been obtained. The formulas for eliminating the noise of the frequency doubled output in phase matching type Ⅱ and type Ⅰ conditions are presented. A general condition concerning the round-trip Jones matrix has been achieved. The eigenvectors for the phase matching type Ⅱ and type Ⅰ have been determined analytically.
