摘　　要：A burst of six pulses with an average power of 38.7 W are obtained for a pulse-burst picosecond 1064 nm laser system at 1 k Hz. The six pulses have equal amplitudes and pulse spacings of 800 ps, the beam quality of the M2 factor is less than 2, and the pulse width is 67 ps. Seed pulses are broadened from 22 to 136 ps by single-pass volume Bragg gratings. A laser-diode end-pump Nd：YVO4 beam-splitting amplifier is used to divide and amplify a single pulse into six pulses. An Nd：YAG regenerative amplifier and a single-pass high-gain amplifier are applied.A burst of six pulses with an average power of 38.7 W are obtained for a pulse-burst picosecond 1064 nm laser system at 1 k Hz.
