我们报道了用电子束光刻法在熔融石英中制作的周期为800 mn的高效透射光栅。在Littrow条件下，在1060 nm波长处，衍射效率达到95%。与传统的镀金衍射光栅相比，其损伤阈值大大提高，使其成为高平均功率（>100 W）飞秒光纤啁啾脉冲放大系统的关键元件。(C)2003年美国光学学会。
We report on highly efficient transmission gratings in fused silica with a grating period of 800 mn generated by electron-beam lithography. At a wavelength of 1060 nm, 95% diffraction efficiency is achieved under Littrow conditions. The damage threshold, extremely enhanced compared with conventional gold-coated diffraction gratings, makes these gratings the key elements in high average power (>100 W) femtosecond fiber chirped-pulse amplification systems.
