三波非共线作用参变过程的相位匹配研究

Study of Phase-Matching of Three-Wave Noncollinear Interactions Optical Parametric Process

对各向异性单轴和双轴非线性晶体中三波非共线作用参变过程的相位匹配进行了详细的研究 ,给出了参变光在非线性晶体主平面内传播的所有非共线参变过程可能的相位匹配类型和相位匹配条件 ,并推出了所有可能的非共线参变过程的临界相位匹配角的解析表达式。

The phase matching for noncollinear optical parametric process was investigated. All the possible phase matching configurations and existence conditions for general noncollinear three-wave mixing interactions were derived for propagation within the crystal principal planes. The calculation expressions for the critical phase matching angles are presented wherever possible.
