| 摘 要： | 双脉冲双向传输放大构型是一种在惯性约束聚变激光驱动器领域具有极大应用价值的新型多程放大技术。针对变形镜代替腔镜对双向传输放大构型两束脉冲波前畸变进行补偿的问题，通过将两束脉冲波前先拼接再补偿的方法，研究出了一种基于双变形镜双哈特曼-夏克传感器耦合控制的新型波前校正技术，并利用神光-Ⅲ主机装置的实测数据进行了模拟验证。结果表明，该技术能够有效控制两束激光传输放大过程中所引入的波前畸变，满足系统对空间滤波器过孔的要求。

| Abstract: | Two-pulse bidirectional propagating amplification architecture, which has great application value in the field of inertial confinement fusion laser driver, is a new type of multi-pass amplification. To solve the problem of correcting two-pulse wavefront distortion with deformable mirrors in cavity position, this paper presents a coupling correcting method with double deformable mirrors and double Hartman-Shack sensors by the way of stitching two-pulse wavefront before compensating. Numerical simulations is carried out with the data of Shenguang-Ⅲ facility. As the result, the coupling correcting technology can effectively control both of two-pulse wavefront distortion and far-field energy distributions in spatial filter pinholes. The conclusion will provide theoretical guidance for designing and building adaptive optics system with two-pulse bidirectional propagating amplification architecture. |
