Abstract

We report on the generation and application of 5-fs pulses at the subterawatt peak power level. A compact all-solid-state femtosecond Ti:sapphire oscillator-amplifier system produces 20-fs, 1.5-mJ pulses. The pulses are subsequently compressed in a hollow-fiber-chirped-mirror compressor. The system delivers bandwidth-limited 5-fs, 0,5-mJ pulses at 780 nm in a diffraction-limited beam. These pulses have been used to investigate the optical damage in dielectrics and the generation of high harmonics in gases down to the water window.
