Abstract

The generation of optical pulses of less than 100-fsec duration in the near-infrared region at wavelengths around 800 nm is reported. These pulses were amplified to microjoule energies at a 6-kHz repetition rate, producing focusable power densities of greater than 1013 W/cm2. A white-light continuum extending into the ultraviolet and infrared regions results when these pulses are focused into a jet of ethylene glycol, opening new possibilities for femtosecond spectroscopic investigations.
