Design of beam sampling grating and study on its diffraction action

  • 摘要: 设计了用于惯性约束核聚变系统的取样光栅。利用光全息学的基本原理,设计了记录全息取样光栅掩模的消像差光学系统,并使用光学设计软件ZEMAX分析了它的像差;还利用严格耦合波理论对取样光栅的衍射效率问题进行了深入的研究。研究发现,在占宽比和槽深这两个光栅结构参量中,槽深的变化对衍射效率更敏感。这些都为取样光栅的实际制作提供了有意义的结果。
    Abstract: The beam sampling grating(BSG) used in the inertial confinement fusion system is designed.By means of optical holographic theory,achromatic optical system recording holographic BSG mask is designed.Its aberration is analyzed with ZEMAX.Meantime,the diffraction efficiency of the BSG is discussed based on rigorous coupled-wave theory.The results show:the groove depth is more important for diffraction efficiency than the duty cycle,which is useful for fabrication of the BSG.
