Numerical Studies on Generation of High Energy Pulses in an All Normal Dispersion Mode-Locked Fiber Laser with and without a Physical Bandpass Filter

摘要

We confirm that pulse generation is possible in an all-fiber, all-normal-dispersion (ANDi) laser without any physical spectral filters. It is also investigated that the ANDi fiber laser without any spectral filters can achieve higher pulse energy and peak power than with the spectral filter if other cavity parameters are the same.
