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 M-2 factor of 1.2. The Nd:YAG crystal with wedge angle of 2 degrees and size of Phi 4x63 mm is adopted in the regenerative amplifier and around by three VCSEL pumping arrays with an angle of 120 degrees. 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 1 ns 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.
