Abstract
We have developed a 100-kHz high-power downchirped-pulse-amplification (DPA) Ti:sapphire laser. A regenerative amplifier, acoustooptically switched and pumped by a Q-switched green laser, is employed for the high-energy amplification with a high repetition rate. Dispersion control is achieved, based on the DPA technique, by use of a prism-grating stretcher and a SF10 glass compressor. We have obtained 28 μJ 45 fs laser pulses at 100 kHz with a compression efficiency of 95%, and further compression down to 20 fs is possible due to the broad amplified spectrum.
