摘要
四个LDA侧面泵浦的Nd3+:YLF激光放大器构成的高增益放大系统,采用双通放大结构,有效抑制了自激辐射,具有较高的信噪比和能量转化效率,实现了对nJ量级注入脉冲的106 以上的高增益放大,具有良好的近场分布与能量稳定性。对系统的工作特性进行了研究,实现了工程化设计,已成功应用于大型ICF驱动器的能量预放大级。
A LDA side-pumped high-gain amplifier system with a dual-pass geometry is reported in this paper. According to the requirement of ICF driver, four ring-LD side-pumping Nd^3+ : YLF amplifiers are used in this system. More than 10^6 gain are achieved when input pulse energy is several nJ at 1 053 nm, the output pulse has good energy stability and perfect near-field distribution.
