| Abstract: | A femtosecond Ti:sapphire chirped pulse amplifier with multipass amplification was developed in this paper, new concepts on overcoming gain-narrowing and enhancing amplification efficience arealso introduced. Pulses of 25fs duration with 36mJ energy have been produced at repetition rates of 10Hz onlyunder 290mJ doubled frequency Nd:YAG laser pump, which corresPOnds to 1. 4TW peak power. |
