Abstract：
A Q-switched Yb:KGW solid-state laser using topological insulator Bi2Se3 as a saturable absorber was demonstrated experimentally for the first time. The Bi2Se3 saturable absorber was fabricated in a film on a highly reflective mirror. By inserting this into a Yb:KGW laser, the Q-switched operation was obtained. The highest average output power was 439.4 mW and the corresponding repetition rate, pulse width and pulse energy were 166.7 kHz, 1.6 mu s and 2.64 mu J, respectively. To our knowledge, this is the highest output power among topological insulator-modulated lasers with topological insulator absorbers.
