Abstract

We report on the first application of a topological insulator based on antimony telluride (Sb₂Te₃) as a saturable absorber (SA) in a bulk microchip laser. The transmission-type SA consisted of a thin film of Sb₂Te₃ (thickness: 3 nm) deposited on a glass substrate by pulsed magnetron sputtering. The saturable absorption of the Sb₂Te₃ film was confirmed for ns-long pulses. The microchip laser was based on a Tm:GdVO₄ crystal diode-pumped at ∼802 nm. In the continuous-wave regime, this laser generated 3.54 W at 1905-1921 nm with a slope efficiency η of 37%. The Q-switched laser generated a maximum average output power of 0.70 W at 1913 nm. The pulse energy and duration were 3.5 μJ and 223 ns, respectively, at a repetition rate of 200 kHz. The Sb₂Te₃ SAs are promising for passively Q-switched waveguide lasers at ∼2 μm.
