Zh. Li et al., Effect of tunable filter characteristics on the pulse performance of actively mode-locked fiber lasers, IEEE PHOTON, 12(11), 2000, pp. 1462-1464
The effect of filter characteristics on the output performance of actively
mode-locked fiber ring lasers has been studied experimentally and numerical
ly, With the same 3-dB bandwidth, the filter that has a flatter wavelength
response tends to generate narrower soliton-like pulses.
