Infrared light pulses as short as 70 fs that are nearly bandwidth limited are obtained in a simple double-pass optical parametric generator with a single β-barium borate nonlinear crystal. Tunability in the 1.2–1.3-μm range is demonstrated with sub-100-fs pulse duration, microjoule pulse energy, and 1-kHz repetition rate.
