| Abstract: | A nanosecond square pulse fiber laser based on the nonlinear amplifying loop mirror(NALM) is numeri-cally analyzed by the nonlinear Schrdinger equation. The fiber cavity with a NALM has a tendency to provide pulse shaping effect with nonlinearity increasing in the NALM,and the nanosecond square pulse is generated by the pulse shaping effect. The numerical results show that the stable square pulse can be obtained when the parameters of the NALM are chosen appropriately. The generated square pulses have flat ... |
