We report on a high energy laser diode (LD) side-continuous-pumped Nd:YAG (yttrium aluminum garnet) picosecond regenerative amplifier. The mode-locking picosecond oscillator is used as seed source with 31.3 ps pulse width, 150 mW average power and 1064.4 nm center wavelengths at the repetition frequency of 86 MHz. For the amplifier system, average output power of 6.4 W and 10.8 W are achieved at repetition frequency of 2 kHz and 4.5 kHz, which corresponds to output pulse energy of 3.2 mJ and 2.4 mJ respectively. The regenerative amplifier designed has high compact and high stability.
