Based on a combined scheme of doubled chirped-pulse amplification and a femtosecond noncollinear opticalparametric amplifier, a high-contrast femtosecond laser pulse with energy of up to 32:3 J has been generated by improving the gain efficiency and boosting the pump energy to 120 J in the final amplifier. Our measurements show that the contrast ratio of the main laser pulse is around 10 10 within the time scale of −400 ps and the duration of compressed pulse is 27:9 fs, corresponding to a peak power of 1:16 PW.
