A compact,low cost,stable noncollinear optical parametric chirped pulse amplification system is studied,which is seeded by an Yb3+-doped self-starting passive mode-locked stacking pulse fiber laser centered at 1 053 nm.A gain higher than 1.1×107, single pulse energy exceeding 11 mJ with fluctuations less than 2% rms ,8 nm amplified signal spectrum are achieved.Different pulse durations of amplified signal are obtained by adjusting the stacker of the Yb3+-doped self-starting passive mode-locked stacking pulse fiber laser.
