A compact high-power picosecond regenerative amplifier based on continuous wave(CW) diode sidepumped Nd:YAG is demonstrated.Average power of 8.8 W is achieved at a repetition rate of 5 kHz at a wavelength of 1 064 nm with a pulse duration of 28 ps,corresponding to a pulse energy of 1.76 mJ and a peak power of 62.9 MW.The beam quality is close to the di?raction limit with Mx2 = 1.24,My2 = 1.03.To the best of our knowledge,this is the highest pulse energy obtained from a CW diode pumped Nd:YAG picosecond regenerative amplifier.
A compact high-power picosecond regenerative amplifier based on continuous wave (CW) diode sidepumped Nd: YAG is characterized. Average power of 8.8 W achieved at a repetition rate of 5 kHz at a wavelength of 1 064 nm with a pulse duration of 28 ps, corresponding to a pulse energy of 1.76 mJ and a peak power of 62.9 MW. The beam quality is close to the di? raction limit with Mx2 = 1.24, My2 = 1.03.To the best of our knowledge, this is the highest pulse energy obtained from a CW diode pumped Nd: YAG picosecond regenerative amplifier.
