摘　　要：通过分析OPO实现参量过程为例,假定晶体周期确定,抽运波长确定,光束传输方向与晶体光轴方向严格平行,分析了温度调谐实际所引起的PPLN-OPO输出波长的偏差.同时也对光轴方向与光束传输方向成小角度的情况作了相应的分析,并对两种情况加以比较.By analyzing the character of the process of OPO, and assuming that the period of the sample and the pump wavelength were certain, the propagation direction was parallel with the optical axis of the crystal firmly, we gained the dispersion of output wavelength of PPLN - OPO which was caused by the change of the temperature in fact. We also analyzed the aspect that the propagation direction departed from the optical axis for a little angle, and compared it with the fornler.
