中文摘要	提出了一种新型的高功率激光装置的预放系统结构,采用钕玻璃再生放大结合离轴四程放大的技术途径,研究了四程放大中寄生振荡和笔形光束的产生机理和抑制措施。通过注入脉宽为3ns,单脉冲能量小于1nJ的1053nm单纵模种子激光,可以获得10.3J的近衍射极限输出,总增益大于10~(10),能量稳定性为2%,输出激光为近平顶分布,近场填充因子为71%,近场调制度约为1.4,91%的焦斑能量能聚焦于2倍衍射极限内。实验结果和输出性能完全满足激光装置预放系统的性能要求,验证了多程放大技术在高功率激光装置预放系统中应用的可行性。
英文摘要	A new laser amplifier structure based on Nd:glass regenerative amplifier and off-axis four-pass amplifier is designed for high power laser facilities.The parasitic oscillation and pencil beam of the four pass amplifier are studied and a method is introduced to suppress them.By injecting a1053 nm single longitudinal mode laser pulse with pulse duration of 3 ns and pulse energy of 1 nJ, a10.3 J amplified pulse with a 2%shot-to-shot energy stability is obtained. The total gain of the amplifier system is over 10~(10). The output laser beam is a flat top profile with a 71%near field fill factor and modulation of 1.4 and 91%pulse energy can be focused into 2 times of diffraction limits.The experimental results and output performance of the amplifier system fully meet the requirements of the pre-amplifier of high power laser facilities, which shows that multi-pass amplifier can be used in high power laser facilities.
