摘要: 采用神光-Ⅲ原型装置“多路放大器级联”的方式，构建了神光-Ⅲ主机装置主放大器构型验证平台。在此平台上开展了小开关隔离能力、主放大系统静态透过率、主放大系统隔离比等性能测试，并且考核了大能量发射时的主放大系统基频光输出能力。结果表明：输出基频光的平均通量达到了神光-Ⅲ主机装置的设计水平，同时验证了神光-Ⅲ主机装置主放大系统构型设计的可行性。Abstract: The main amplifier configuration verification platform of Shenguang-Ⅲ(SG-Ⅲ) laser facility is constructed by multi-path amplifier connection of SG-Ⅲ prototype facility. Based on this platform, the isolation ability of small switch, and the static transmission rate, isolation ratio and energy output capability of main amplifier system are tested. The result shows that, the beam average fluence of 1ω output meets the designed level of SG-Ⅲ laser facility and the effectiveness of SG-Ⅲ main amplifier configuration is verified.
