Pulse compressed gratings (PCG) used in chirped-pulse amplification system and based on multi-layer thin film stack are etched with ion-beam and holographic techniques.
应用于啁啾脉冲放大技术中的脉宽压缩光栅是基于多层膜作为基底，利用全息干涉技术和离子束技术刻蚀而成。
It is also found that replacement of substrate and adjustment of film stack structure would lead to the change of drift, this will enhance the temperature stability of filter.
同时经过计算分析发现通过更换膜系基板和调整膜系结构可以改变滤光片中心波长的漂移，这个结果有助于提高滤光片的温度稳定性。
