In SULF-10 PW laser facility, different methods are adopted to suppress different kinds of noise. Nonlinear pulse temporal filter based cascaded XPWG and fs-OPA techniques is utilized to suppress the ASE noise. While novel multi-pass amplifiers with wedged Ti:sapphire crystals are employed to suppress the pre-pulses in both nanosecond and picosecond domain. Applying these methods, temporal contrast about the ASE noise and the pre-pulses can reach 10-11 and 10-10 in SULF-10 PW laser, respectively.
