A Ti:Al2O3 chirped-pulse amplification system is used to simultaneously image and machine. By combining simultaneous spatial and temporal focusing (SSTF) with spatial frequency modulation for imaging (SPIFI), we are able to decouple the imaging and cutting beams to attain a resolution and a field-of-view that is independent of the cutting beam, while maintaining single-element detection. This setup allows for real-time feedback with the potential for simultaneous nonlinear imaging and imaging through scattering media. The novel SSTF machining platform uses refractive optics that, in general, are prohibitive for energetic, amplified pulses that might otherwise compromise the integrity of the focus as a result of nonlinear effects.
一个钛宝石啁啾脉冲放大系统用于同时进行成像和加工。通过将同时空聚焦（SSTF）与用于成像的空间频率调制（SPIFI）相结合，我们能够解耦成像光束和切割光束，以获得与切割光束无关的分辨率和视场，同时保持单元素检测。这种设置允许进行实时反馈，具有同时进行非线性成像和透过散射介质成像的潜力。这种新型的SSTF加工平台使用折射光学元件，一般来说，对于高能、放大脉冲是不适用的，否则这些脉冲可能会由于非线性效应而损害焦点的完整性。
