Abstract:The design and simulation of an all-fiber ytterbium doped passively mode -locked fiber laser were presented which generated ultrashort pulses as the laser seed.The passive mode -locking was achieved by using the nonlinear polarization technology,and the normal dispersion was compensated by the all solid photonic bandgap fiber.As a result of the simulation and optimization,the ytterbium doped fiber laser generated the 0.7ps pulses with 0.89nJ energy.The simulation results suggest that the passive mode -locking method and the dispersion compensation method are useful for achieving the ultrashort pulses which meet the requirements to be the laser seed.
