Based on the optical rotatory dispersion effect, an optical filter for selecting the second harmonic of a frequency-doubled laser is constructed from quartz in combination with polarizers. The operating principle is analyzed by matrix formulation, and the result indicates that the second harmonic of a frequency-doubled laser will be obtained when the rotation angle has a difference of (2n 1)'pi'/2 (n=0, 1, 2, 3, ...) between the two polarizations of the second-harmonic laser and the fundamental laser. The spectrum of the output laser is taken by the AQ-6315A spectrometer, and the experimental results are in good agreement with the theoretical results.

选取4块反射型体相位光栅,两两配对分为两组,各组中的光栅条纹面相互垂直,光栅矢量面正交放置,构成反射型体相位光栅空间低通滤波装置,被用来实现连续激光光束二维空间低通滤波的功能。利用Kogelnik耦合波理论,分析了上述装置对连续激光光束的空间低通滤波性能,并模拟了其对畸变高斯光束的空间低通滤波效果。结果表明,采用这种装置可使得畸变高频角谱成分具有极低的衍射效率,而对有用低频角谱成分具有高达98%以上的衍射效率,能够达到不须对入射光束聚焦就能实现高、低频角谱成分空间分离的目的,从而使得滤波后的光束较未畸变光

随着极紫外(EUV)光刻物镜的设计朝着组合倍率物镜系统的方向发展,物镜系统需要同时具有大视场和高数值孔径(NA),因而产生了物镜的光线入射角及入射角范围急剧增大的问题,需要研究适用于组合倍率极紫外光刻物镜系统的膜层设计的新方法。提出了渐进优化膜层的设计方法,该方法提高了镀制膜层的物镜系统的反射率,保证了组合倍率物镜系统的成像质量。利用该方法对NA为0.6的组合倍率物镜系统进行了膜层设计,设计结果表明,含膜极紫外光刻物镜系统的平均反射率大于65%,各反射镜的反射率峰谷值均小于3.35%,反射率均匀性良好。
