摘要： A self-pulsed Tm:GdScO$_{3}$ laser was experimentally demonstrated by using a compact linear resonant cavity. When the pump power was 19.6 W, an average output power of 1771 mW was achieved from the self-pulsed Tm:GdScO$_{3}$ laser with a pulse width of 158.1 ns and a pulse repetition frequency of 112.8 kHz, corresponding to an optical-to-optical conversion efficiency of 9.0%. Moreover, a single pulse energy of 15.7 μJ and a pulse peak power of 99.3 W were acquired from the self-pulsed Tm:GdScO$_{3}$ laser. This is, as we know, the first time that the self-pulsed laser output at 2-μm waveband range was obtained by utilizing a Tm:GdScO$_{3}$ crystal so far.
