摘　　要：Bismuth nanosheets(Bi-NSs) were successfully prepared and employed as saturable absorbers to generate a diodepumped dual-wavelength Er^(3+):SrF_2 laser in the mid-infrared region. Q-switched pulses with a maximum output power of 0.226 W were obtained at an absorbed pump power of 1.97 W. A repetition rate of 56.20 kHz and a minimum pulse duration of 980 ns were achieved. To the best of our knowledge, we present the first application of Bi-NSs in a mid-infrared all-solid-state laser. The results prove that Bi-NSs may be applied as an optical modulator in mid-infrared photonic devices or as a mode-locker and Q-switcher.Bismuth nanosheets （Bi-NSs） were successfully prepared and employed as saturable absorbers to generate a diodepumped dual-wavelength Er^3＋ ：SrF2 laser in the mid-infrared region.
