摘要
建立了实际刻划光栅的物理模型,给出了相应的衍射效率表达式,分析了零级面对闪耀光栅衍射效率的影响。在工艺过程中,通过有效控制零级面成功研制了10.6μm激光器一级输出和9.77μm激光器零级输出选频振荡闪耀光栅。
The physical model of real nded grating is purposed, the corresponding expression of diffraction efficiency is given, and the influence of zero-order plane on diffraction efficiency of the blazed grating is analyzed. In the process of technology, select frequency oscillation blazed gratings with the zero-order couple by 9.77μm laser and the first-order couple by 10.6μm laser are manufactured by controlling the zero-order plane.
