论文摘要
我们塑造FS光学脉冲,并以单个空间模式传递到多模纤维的输入。脉冲会在时间上形状,使得在多模纤维的输出下,超短脉冲出现在预定义的焦点处。我们的结果显示了如何在僵硬的一块平方核步数多模纤维的输出处进行栅格扫描一个超平脉冲,并以这种方式使制造光纤后面场景的非线性荧光图像的潜力可以通过薄且灵活的单模纤维建立,而与多模板光纤的连接可以建立。实验结果符合我们的数值模拟。
We shape fs optical pulses and deliver them in a single spatial mode to the input of a multimode fiber. The pulse is shaped in time such that at the output of the multimode fiber an ultrashort pulse appears at a predefined focus. Our result shows how to raster scan an ultrashort pulse at the output of a stiff piece of square-core step-index multimode fiber and in this way the potential for making a nonlinear fluorescent image of the scene behind the fiber, while the connection to the multimode fiber can be established via a thin and flexible single-mode fiber. The experimental results match our numerical simulation well.
