Abstract
An optical parametric amplifier system pumped by 1 kHz, 8 mJ femtosecond laser pulses at 800 nm has been constructed to generate high intensity, infrared pulses (~ 3 mJ, 1400 nm, 40 fs) with a total conversion efficiency of ~ 40%. The femtosecond high intensity laser pulses at 800 nm and 1400 nm have been used for high order harmonic generation in a semi-infinitive gas cell and have allowed the achievement of bright phase-matched harmonic radiation in the extremeultraviolet and soft X-ray region.
