| Abstract: | An efficient chirped-pulse amplification, Ti: sapphire laser system, has been developed using mainly domestic components.
The gain-narrowing effect has been significantly overcome by shaping spectrum of seeding pulses. With a novel aberration-free
stretcher and two stage multi-pass amplifiers, pulses with duration of 25 fs and 36-mJ energy have been obtained at 10 Hz
repetition rate, using only less than 290 mJ green Nd:YAG pump energy. This corresponds to a 1.4 TW peak power and 32% main
amplification efficiency. The energy stability of the laser systems is better than ± 3%. |
