Abstract
A Ti:sapphire mode-locked regenerative amplifier system pumped with a single argon-ion laser produces 4-mu J, 170-fs pulse of 800-nm wavelen gth at a 250-kHz repetition rate. Part of this output is used to gener ate a high-beam-quality white-light continuum, while the rest is doubl ed to 400 nm and used to parametrically amplify visible components of this continuum to more than 100 nJ. Synchronized with the visible sign al pulse tunable from 460 to 700 nm is an infrared idler pulse tunable from 2.4 to 0.9 mu m.
