In this work, we demonstrate a passively-Q-switched 1.33 mu m Nd:Lu2YSc1.5Ga3.5O12(Nd:LuYSGG) laser based on the Bi(2)Se(3)topological insulator (TI) as a saturable absorber (SA). We obtain pulse widths as low as 146 ns at a pulse repetition rate of 349.5 kHz and a pulse energy of 1.03 mu J, which provides a peak power of 7.05 W. These results represent some of best yet published in terms of repetition rate, pulse width, and peak power for TI-basedQ-switched 1.3 mu m lasers, which indicates that TIs are suitable as SAs in the 1.3 mu m region.
