摘　　要：We demonstrate a dual-wavelength passively Q-switched Nd^（3＋）-doped glass fiber laser using a few-layer topological insulator Bi2Se3 as a saturable absorber（SA） for the first time, to the best of our knowledge. The laser resonator is a simple and compact linear cavity using two fiber end-facet mirrors. The SA is fabricated by Bi2Se3/polyvinyl alcohol composite film. By inserting the SA into the laser cavity, a stable Q-switching operation is achieved with the shortest pulse width and maximum pulse repetition rate of 601 ns and 205.2 kHz,respectively. The maximum average output power and maximum pulse energy obtained are about 6.6 mW and 38.8 nJ, respectively.We demonstrate a dual-wavelength passively Q-switched Nd^（3＋）-doped glass fiber laser using a few-layer topological insulator Bi2Se3 as a saturable absorber（SA） for the first time, to the best of our knowledge.
