| Summary: | An in-band pumped 1.645-μm Er:YAG ceramic laser passively Q-switched by a topological insulator: Bi<sub>2</sub>Te<sub>3</sub> saturable absorber is reported. The average output power could reach up to 210 mW, corresponding to a pulsewidth, a pulse repetition rate, and a per-pulse energy of 6.3 μs, 40.7 kHz, and 5.3 μJ, respectively. This result indicates that the topological insulator: Bi<sub>2</sub>Te<sub>3</sub> could be a promising saturable absorber such as graphene, with potential applications for solid-state lasers. |
