英文摘要：

Based on the coupled Ginzburg-Landau equation,the pulse dynamic behavior which was generated from graphene mode-locked fiber laser was studied in detail.Firstly,the solution form of chirped bright-bright soliton pairs was achieved by using ansatz method.Secondly,the transmission characteristics and stability of chirped bright-bright soliton pairs were discussed by using simulating method.The results showed that the exact solution of chirped bright-bright soliton pairs could be obtained after the system parameters were chosen correctly,and it could also be transmitting stably under definite disturbances.These results could provide certain theoretical references for designing and improving the performance of grapgene mode-locked fiber lasers.
