Abstract
Investigations of optical solitons have always been a hot topic due to their important
scientific research value. In recent years, ultrafast lasers based on
two-dimensional materials such as saturable absorbers (SAs) have
become the focus of optical soliton research. In this work, various
soliton operations are demonstrated in Er-doped fiber lasers (EDFLs)
based on SAs. First, a low-threshold passively
mode-locked EDFL with traditional soliton output is constructed, and
the pump threshold is as low as 10.1 mW. Second, by adjusting
the net dispersion of the cavity, stable dissipative soliton operation
can also be obtained. Traditional soliton mode-locked operation with
controllable Kelly sidebands from first order to fourth order is
realized by adjusting the pump power in a double-ended pumped
structure, and the SNR is as high as 55 dB. All results prove
that used as SA material has great
potential and wide application prospects in investigating optical
soliton operations in mode-locked fiber lasers with both normal and
anomalous dispersion.
