摘　　要：从理论上研究了近简并区内倍频YAG激光(532nm)泵浦KTP晶体光参量振荡器位相匹配的实现。得到了这个区域内在KTP晶体中Ⅱ(A)类和Ⅱ(B)类相互作用的条件,同时计算了Ⅱ(B)类相互作用的参量调谐范围、走离角和有效非线性系数。We have realized the phase matching of optical parametric oscillator in KTP crystal pumped by doubled YAG laser in the quasi-degenerate region theoretically and obtained the condition of interactions of Type Ⅱ (A) and Type Ⅱ (B) in KTP in this region. The tuning region of wavelength, walk-off angle, and effective nonlinear coefficient for Type Ⅱ (B) interaction are numerically calculated.
