【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]:Dual-pulse bidirectional transmission amplifier configuration is a new type of multi-pass amplification technique with great application value in inertial confinement fusion laser driver. Two-pulse wavefront is transmitted bidirectionally by deformable mirror instead of mirror. The problem of compensation for distortion, A novel wavefront correction technique based on dual deformable mirror dual Hartmann-Shaq sensor coupling control is developed by splicing and compensating two beams of pulse wavefront. The experimental data of Shenguang-鈪，
