Based on the Ginzburg-Landau equation, the limitation of the B integral issue is studied via numerical simulation for 100 kHz fiber chirped pulse amplification system. The compressibility of the pulse with the B integral under the typical amplifier structure is analyzed. The B integral limitation for 1 ns stretched pulse and 1 ps compressed pulse is given to be around 40 rad. A multi-pulse scheme is proposed to suppress the B integral of each pulse and is verified by theoretical simulation.
