Abstract

Summary form only given. 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.
