An electro-optic (EO) Q-switched Nd:YVO₄ laser with high repetition rate of 30 kHz,end-pumped by a continuous-wave (CW) laser diode (LD) is reported. Using La3Ga5SiO14(LGS) single crystal as an EO Q-switch and designing an efficient and stable resonator,the repetition rate of EO Q-switched operation can be changed from 1 Hz to 30 kHz. Using an output coupler with transmittance of 50%,an output pulse train with pulse energy of 0.4 mJ and pulse width of 6.3 ns is obtained at the repetition rate of 5 kHz. An average output power of 6.2 W with the pulse width of 9.1 ns is obtained when the repetition rate reaches 30 kHz,the slope efficiency and dynamic to static ratio are 32.7% and 83%,respectively. The beam transfer factor M2 is measured to be less than 2. Experimental results show that the output level has great potential for further development.
