摘要

We present the performance of a high-power Nd:glass laser system,which produces a 1.1 J,250 fs,7.3 nm broadband laser pulse based on the combination of optical parametric amplification (OPA) and chirped pulse amplification (CPA).The two-stage OPA provides broadband seed pulses for the three-stage Nd:glass amplifiers based on the technology of CPA.Compared to the conventional oscillator seed source,the most important advantage of such a seed source supplied by the two-stage OPA is that it possesses the capacities of broad bandwidth and high energy.
