Abstract

In this study, (TiS) polyvinyl alcohol (PVA) film-type (SA) is synthesized with a modulation depth of 5.08% and a saturable intensity of 10.62 MW/cm by liquid-phase exfoliation and spin-coating methods. Since TiS-based SA has a strong nonlinear saturable absorption property, two types of optical soliton were observed in a mode-locked Er-doped . When the pump power was raised to 67.3 mW, a conventional mode-locked pulse train with a repetition rate of 1.716 MHz and a pulse width of 6.57 ps was generated, and the output spectrum centered at 1556.98 nm and 0.466 nm spectral width with obvious Kelly sidebands was obtained. Another type of mode-locked pulse train with the maximum output power of 3.92 mW and pulse energy of 2.28 nJ at the pump power of 517.2 mW was achieved when the polarization controllers were adjusted. Since TiS-based SA has excellent nonlinear saturable absorption characteristics, broad applications in ultrafast photonic are expected.
