摘      要：For the first time,a group-Ⅵsingle element nanomaterial was used as the optical saturable absorber(SA)to generate laser *** two-dimensional(2D)tellurene as a passive Q-switch,1.06μm and 1.3μm pulse laser operations were realized from a diode-pumped Nd:YAG *** shortest pulse widths were 98 ns and 178 ns,and the highest peak powers were 2.68 W and 2.45 W,*** research determines that tellurene is an excellent SA material in the near-infrared region.
