In our work, a new-type, to the best of knowledge, ferromagnetic insulator and its nonlinear optical absorption characteristics related ultrafast modulation applications were investigated. Cr2Si2Te6 saturable absorbers (SAs) with depth intensity 9.7% 3.5MW/cm2 fabricated. By adjusting pump power 120 mW optimizing polarization state, traditional soliton operations obtained successfully; corresponding duration pulse fundamental repetition rate ∼1.33ps 6.70 MHz, signal-to-noise ratio was 50 dB....

In this paper, an indium antimonide (InSb) saturable absorber (SA) was successfully fabricated. The absorption properties of the InSb SA were studied, and they show a modulation depth intensity 5.17% 9.23MW/cm2, respectively. By employing building ring cavity laser structure, bright-dark soliton operations obtained by increasing pump power to 100.4 mW adjusting polarization controller. As increased from 180.3 mW, average output 4.69 9.42 corresponding fundamental repetition rate 2.85 MHz,...
In this work, a saturable absorber (SA) based on Cr2Si2Te6 (CST), with modulation depth of 14.90% and saturation intensity 4.81MW/cm2, was prepared by liquid phase stripping method. Its nonlinear optical properties application in obtaining mode-locked pulse output bright-dark solitons are studied. When the pump power 1250 mW, maximum 26.60 mW; energy single 15.02 nJ, repetition rate 1.77 MHz. Our results provided evidence that CST can be used as an excellent SA for laser demonstrated...
Recently, germanium (Ge) was also considered as the two-dimensional (2D) material saturable absorber (SA) because of its excellent nonlinear absorption properties. However, research Ge SA Er-doped fiber laser is still rare. In this work, bound state solitons were demonstrated in laser. To be best our knowledge, no previous work has ever achieved that. Three kinds with 9.77 MHz fundamental frequency investigated, indicating that optical characteristics to promote development soliton.
