The research work of LD pumped Tm∶YAP laser is reported. Tm∶YAP laser is end pumped by LD with wavelength of 793 nm, and acoustooptic Q-switched operation in the cavity. When the laser repetition frequency is 300 Hz and the input pump power is 37.07 W, a 1936 nm laser output with a maximum single pulse energy of 17.06 mJ and a pulse width of 26.9 ns is obtained, and the corresponding peak power is 634.2 kW, which is higher than the reported peak power values of this crystal. At the maximum input pump power, the beam quality factors for horizontal and vertical directions were 1.41 and 1.34, respectively. In addition, under the continuous operation of the laser, a double Fabry-Perot etalon is used to adjust the laser wavelength, and the spectral tuning range is 1932.11-1942.07 nm.
