We report the generation of kilohertz-rate, amplified, sub-100-fsec-duration laser pulses tunable from 785 to 825 nm. A novel two-stage amplification scheme is used to produce amplified, tunable optical pulses, with microjoule energies. Diffraction-limited focusing of the amplified laser pulses in ethylene glycol to peak intensities greater than 10/sup 13/ W/cm/sup 2/ results in the efficient generation of white-light continuum pulses with a bandwidth extending from 0.4 to 1.0 /mu/m. This tunable laser system is well suited for sensitive femtosecond spectroscopic measurements in the near infrared, and its tunability may easily be extended to cover the wavelength range 600--900 nm.
