We report a diode-end-pumped Q-switched YVO4/Nd:YVO4/YVO4 self-Raman second-Stokes laser at the wavelength of 1764 nm. With the incident pump power of 32 W and the pulse repetition frequency of 20 kHz, the maximal average output power at 1764 nm is up to 1.18 W, with the corresponding optical conversion efficiency of 3.69%. The highest pulse energy and peak power are 59 mJ and 31.7 kW, respectively.
