In this paper, we report on a high-power Tm : YAP cavity-dumped laser capable of simultaneously achieving high repetition rates and short nanosecond pulses. The laser employs a Pockels cell (PC) composed of a La3Ga5SiO14 (LGS) crystals as an electro-optical Q-switch, which overcomes the limitations of piezoelectric ringing effects on the highest operating repetition rates and thermally-induced depolarization on the maximum operating power. A stabilized pulsed laser output at 1942 nm, with a pulse repetition rate of 20 kHz, a pulse duration of 6.0 ns, and an average output power of 15.0 W, is obtained at a pump power of 150 W. The beam quality factor M2 is 1.36 in the vertical direction and 1.18 in the horizontal direction.
