摘要
针对惯性约束聚变(ICF)驱动器对谐波分离的苛刻要求,利用基于矢量衍射理论开发的商用软件Gsolver,在布拉格(Bragg)入射角下,设计满足分光要求的光栅参数,并根据对影响谐波分离性能的亚波长光栅的各个参数进行了分析,研究了实现谐波分离的亚波长光栅的优化设计方法,并设计得到了满足谐波分离要求的亚波长光栅。研究结果为亚波长光栅用于谐波分离提供了理论支持。
The sub-wavelength grating was designed,which adapting the harsh requirement of harmonic waves separating in inertial confinement fusion （ICF） drivers. Using the commercial software Gsolver which was developed on the basis of vector diffraction theory,the parameters of sub-wavelength grating which would influence separate harmonic waves,were analysed. The design method of sub-wavelength grating for separating harmonic waves was studied. These results offer the supports for the sub-wavelength grating design.
