本文首次研究了基于独立反射棱镜的压缩器，用于补偿多光子显微镜中的群延迟色散（GDD）和三阶色散（TOD）。通过一对反射光栅改进色散管理，使我们能够在800 nm处获得负4000fs 2和10000fs 2 GDD，这正是典型多光子显微镜引起的色散量。所获得的GDD值是使用紧凑的尺寸设置比其他报告的设计。此外，系统还提供21fs和225fs的负TOD，用于相应的GDD补偿。
We studied the independent reflection grism based compressor in order to compensate Group Delay Dispersion (GDD) and Third Order Dispersion (TOD) in multiphoton microscopy, to our knowledge, for the first time. Improved dispersion management by means of a pair of reflection grisms allowed us to obtain negative 4000fs 2 and 10000fs 2 GDD at 800 nm which are just about the amount of dispersion induced by a typical multiphoton microscope. The obtained GDD values are achieved using compact size setup than other reported design. Moreover, the system also provides 21fs and 225fs negative TOD for corresponding GDD compensation.
