摘要

We report a high-contrast, high-intensity Ti:sapphire chirped-pulse ampliﬁcation system that incorporates annonlinear preampliﬁer based on optical parametric chirped-pulse ampliﬁcation (OPCPA). By cooling thenTi:sapphire crystal in the ﬁnal ampliﬁer down to 77 K, the chirped-pulses are ampliﬁed to 2.9 J at a 10Hznrepetition rate without a thermal lensing effect. Pulse compression down to 19 fs duration obtained afternampliﬁcation indicates a peak power of 80 TW. With the OPCPA, the temporal contrast is signiﬁcantly im-nproved to better than 7u000110−9 in a few picoseconds interval prior to the main laser pulse. © 2008 OpticalnSociety of America
