This paper reports the cavity-dumped mode-locked picosecond laser with single pulse energy greater than 10 μJ for the first time in China, to the best of our knowledge. We complete semiconductor saturable absorption mirror (SESAM) mode-locked high-power picosecond laser oscillator with a fiber-coupled laser diode end-pumped Nd:YVO4 crystal. Then we insert BBO electro-optic crystal to the clamping cavity, realizing the repetition frequency 1 Hz~10 kHz continuously adjustable electro-optical cavity-dumped mode-locked operation. When the pump power is 17.9 W, pulses with single pulse energy of 12.5 μJ and repetition frequency of 10 kHz are obtained, whose pulse width is about 24.7 ps.
