英文摘要	experimental investigations of nondegenerate ultrabroadband chirped pulse optical parametric amplification have been carried out. the general mathematical expressions for evaluating parametric bandwidth, gain and gain bandwidth for arbitrary three-wave mixing parametric amplifiers are presented. in our experiments, a type-i noncollinear phase-matched optical parametric amplifier based on lithium triborate, which was pumped by a 5-ns second harmonic pulses from a q-switched nd:yag operating at 10 hz, seeded by a 14-fs ti:sapphire laser at 800 nm, was presented. the 0.85 nj energy of input chirped signal pulse with 57-fwhm has been amplified to 3.1 muj at pump intensity 3 gw/cm(2), the corresponding parametric gain reached 3.6 x 10(3), the 53 nm-fwhm gain spectrum bandwidth of output signal has been obtained. the large gain and broad gain bandwidth, which have been confirmed experimentally, provide great potentials to amplify efficiently the broad bandwidth femtosecond light pulses to generate new extremes in power, intensity, and pulse duration using optical parametric chirped pulse amplifiers pumped by powerful nanosecond systems.
