摘要：
A high-pulse-energy, diode-pumped, solid-state Nd3+:Y3Al5O12 (Nd:YAG) two-pass amplifier system without water cooler was demonstrated in this study. The modulation of LD and Nd:YAG crystal rod and the use of thermoelectric cooler(TEC) in whole system aimed to make the system miniaturized. The cavity length was 280 mm. And a 350 mJ laser pulse was obtained with a pulse duration of 9.7 ns, a frequency of 10 Hz and a beam quality M2 of 7.7 and 12.3 for horizontal and vertical directions, respectively. A 740 mJ, 10 ns laser pulse for two-pass amplification was obtained. © 2018, Science Press. All right reserved.
