摘要：

We have demonstrated ultra-broadband optical parametric chirped-pulse amplification of more than 350 nm bandwidth in the near-infrared region. We have observed a substantial enhancement (nearly 2-fold) of the parametric amplification bandwidth by using time-delayed two broadband pump pulses at degeneracy.
