中文摘要以薄膜光学的干涉理论和衍射光学的傅里叶模式理论为基础,给出了0.8μm飞秒激光器用多层介质膜脉宽压缩光栅的理论设计;设计采用H3L(HL)^9H0.5L2.4H的多层介质膜为基底,当刻蚀后表面浮雕结构的占宽比为0.35,线密度为1480线/mm,槽深为0.2μm,顶层HfO2的剩余厚度为0.15μm时,对于Littrow角度(36.7°)和TE波模式入射的衍射光栅其-1级衍射效率达到95%以上.; Based on optical interference theory and Fourier modal theory, a new multi-layer dielectric gratings is designed for use in femtosecond laser system at wavelength 0.8 mu m. A multi-layer dielectric with stack of H3L(HL)<^>9H0.5L2.4H is used as a substrate to be etched with corrugated structure. Numerical computation indicates that the diffraction efficiency of - I order can be more than 95% when the parameters of multi-layer dielectric grating are the following: laser is incident on-the grating at 36.7 degrees in TE mode, the duty cycle is 0.35 and the line density is 1480/mm, the groove depth is 0.2 mu m and the top residual HfO2 is 0.15 mu m.
