As walk-off angle and acceptance angle of beam limit the conversion efficiency and the tunable wavelength range of difference frequency generation, research include effective nonlinear coefficient, walk-off angle and acceptance angle as functions of wavelength, the relationship between conversion efficiency and acceptance angle, and the impact of crystals length on the process of frequency conversion.

由于光束的走离角、允许角限制了转换效率和差频调谐波长范围，研究内容还涉及了有效非线性系数、走离角和允许角与波长的关系，转换效率与允许角的关系，以及晶体长度在频率变换过程中产生的影响。
