Abstract

In our work, a new-type, to the best of our knowledge, ferromagnetic insulator and its nonlinear optical absorption characteristics and related ultrafast modulation applications were investigated. ${{\rm Cr}_2}{{\rm Si}_2}{{\rm Te}_6}$ saturable absorbers (SAs) with a modulation depth and a saturable intensity of 9.7% and ${3.5}\;{{\rm MW/cm}^2}$ were fabricated. By adjusting the pump power to 120 mW and optimizing the polarization state, traditional soliton operations were obtained successfully; the corresponding duration of pulse and the fundamental repetition rate were ${\sim} {1.33}\;{\rm ps}$ and 6.70 MHz, and the signal-to-noise ratio was 50 dB. The experimental results reveal that ${{\rm Cr}_2}{{\rm Si}_2}{{\rm Te}_6}$ with excellent saturable absorption characteristics can be used as a SA to obtain ultrafast pulse lasers.
