Paper Abstract

A four-pulses sequence picosecond 1064nm regenerative amplifier system with repetition rate of 1 kHz are obtained, which with the average power of 9.2 W and beam quality M2 factor of 1.2. The Nd: YAG crystal with wedge angle of 2° and size of Φ 4×63 mm is adopted in the regenerative amplifier and around by three VCSEL pumping arrays with an angle of 120°. A laser diode (LD) pumped Nd: YVO4 crystal SESAM mode-locked seed laser is broadened from 20 to 260 ps by double-pass Volume Bragg Gratings and divided into equal amplitudes four-pulse sequence with the pulse spacing of 1ns by beam splitter mirrors. The four-pulse sequence enters the regenerative amplifier in order and the power is amplified from 0.68 to 9.5 W.
