我们报告了具有 SiO2 雕刻层的色散镜 (DM) 的设计、制造和应用。 DM 的群延迟色散 (GDD) 在 680 至 920 nm 的光谱范围内为 -200 fs2。设计并制造了具有多层结构的 DM，该结构由 SiO2 雕刻层组成，该层的折射率约为 1.09，通过掠射角沉积 (GLAD) 制造，位于通过双离子束溅射制造的传统啁啾薄膜叠层之上。与没有 SiO2 雕刻层的传统啁啾薄膜叠层相比，DM 的 GDD 振荡可以显着降低，同时保持数百飞秒平方的大 GDD 和宽色散带宽。首次将带有SiO2雕刻层的单DM成功应用于光纤啁啾系统，无需使用DM-pair，可实现激光脉冲压缩至16fs。
We report on the design, fabrication and application of dispersive mirrors (DMs) with a SiO2 sculptured layer. The group delay dispersion (GDD) of the DMs are -200 fs2 in the spectral range from 680 to 920 nm. DMs with a multilayer structure consisting of a SiO2 sculptured layer with a low refractive index of ~1.09 fabricated by glancing-angle deposition (GLAD) on top of a conventional chirped film stack fabricated by dual-ion beam sputtering are designed and fabricated. The GDD oscillations of the DMs could be significantly reduced compared to the conventional chirped film stack without the SiO2 sculptured layer while maintaining a large GDD of several hundred femtoseconds squared and a wide dispersion bandwidth. For the first time, a single DM with a SiO2 sculptured layer has been successfully applied in a fiber chirped system without being used in DM-pair, which can realize the compression of laser pulses to 16fs.
