摘要:
Noncollinear difference frequency mixing is reported for the first time in a barium borate crystal that generates near‐infrared radiation tunable from 2.04 to 3.42 &mgr;m. The technique apart from verifying a very simple relation correlating the phase‐matching angle with the noncollinear angle of the interacting beams provides a simple alternative scheme for generating coherent radiation in this important spectral range.
