摘　　要：将基于石墨烯材料的锁模器件视作特殊光纤，对光纤激光器内各个部分建立了统一的数值模型，采用“脉冲追踪”方法对光纤腔内超短脉冲的传播过程进行模拟，得到的结果与已报道实验现象相符，并利用程序研究了石墨烯锁模器件主要参数对脉冲特性的影响规律，对搭建和优化锁模装置有一定的指导意义。Taking mode lockers based on graphene as special fibers, a uniform numerical model of the sub-units in mode-locked fiber lasers is set up. The forming process of mode-locked pulse has be simulated with a so-called pulse tracing method. The results coincide with experimental phenomenoln reported previously. After that, some research on the relation between graphene mode-locker parameters and pulse character has been done, which is helpful for constructing and optimizing laser device.
