对于用于光学参数生成的 /spl β/-硼酸钡 (BaB/sub 2/O/sub 4/) 晶体，在 400 nm 泵浦时；使用泵浦信号角约为 3.7" 的非共线相位匹配，相位匹配角在大部分可见光范围内变得与波长无关。最近，利用这一特性在可见光中构建宽带非共线 OPA，实现短至 16 fs 的脉冲。
For a /spl beta/-barium borate (BaB/sub 2/O/sub 4/) crystal employed in optical parametric generation, when pumped at 400 nm; using noncollinear phase matching with a pump-signal angle around 3.7", the phase-matching angle becomes independent of wavelength over most of the visible. Recently, this property was exploited to build broadband noncollinear OPAs in the visible, achieving pulses as short as 16 fs.
