摘要：
Tunable mid-IR pulses in the range 1300-4200 cm(-1) (7.7-2.4 mum) are generated through a phase-matched four-wave mixing process in ordinary mid-IR window materials such as CaF2 and BaF2. In this process the difference frequency nu (3) = 2 nu (2) - nu (1) is generated from pump fields nu (1) and nu (2). The process can be phase matched to different frequencies by adjustment of the angle between the pump fields. (C) 2001 Optical Society of America.
