| 摘 要： | We study a femtosecond Ti：sapphire laser pumped optical parametric amplifier （OPA） at 1053nm. The OPA Generates stable signal pulses with duration smaller than l OOfs, wavelength drift smaller than 0.5 nm, and pulseto-pulse fluctuation of about ±4%, by employinG an external seeder. In a terawatt laser pumped large-aperture LiNbOa OPA, pulse energy at signal has been scaled up to 4mJ. This m J-class femtosecond OPA at 1053nm presents a feasible alternative to optical parametric chirped-pulse amplification, and is ready to be applied to petawatt lasers.
