摘　　要：基于三波耦合的能量、动量守恒条件和KBe2BO3F2(KBBF)晶体最新的色散方程,研究了共线Ⅰ类、Ⅱ类相位匹配和非共线Ⅰ类相位匹配KBBF晶体的角度调谐曲线;并比较了共线相位匹配和非共线相位匹配的特点.Based on the laws of momentum and energy conversion for phase matching condition and the newest Sellmeier equations of （KBBF）crystal, the angle tuning curves of KBBF crystal for type I and type II for collinear phase matching, type I for noncollinear phase matching conditions are studied. T;he characteristics of collinear phase matching and noncollinear phase matching are also pointed out.
