Abstract
We report on a femtosecond Ti:sapphire laser amplifier system that gen erates pulse energies >5 mJ at a 1-kHz repetition rate. The system con sists of regenerative and multipass amplifiers and uses the technique of chirped-pulse amplification. When the system was seeded with 70-fs pulses at 800 nm from a self-mode-locked Ti:sapphire oscillator, ampli fied pulses of 94-fs duration at a repetition rate of 1 kHz and an ave rage output power of 5.4 W were produced. The amplified pulse-repetiti on rate is variable from 250 Hz to 3 kHz. Pulse energies of >7.5 mJ we re obtained at 500 and 250 Hz. (C) 1997 Optical Society of America.
