论文摘要
在这项工作中,我们使用较少数量的平坦窗口来展示一个离散的分散扫描方案,以在离散步骤中改变激光脉冲的分散。蒙特卡洛模拟表明,可以在少于10个色散步骤中准确检索脉冲持续时间,我们通过在3和10微米波长下测量几个周期脉冲和材料分散曲线来实验验证。这种最少的测量方案仅使用五个光学组件,而无需高精度定位器和干涉比对,可以在许多波长范围和情况下很容易实现。
In this work, we demonstrate a discrete dispersion scan scheme using a low number of flat windows to vary the dispersion of laser pulses in discrete steps. Monte Carlo simulations indicate that the pulse duration can be retrieved accurately with less than 10 dispersion steps, which we verify experimentally by measuring few-cycle pulses and material dispersion curves at 3 and 10 micrometer wavelength. This minimal measuring scheme using only five optical components without the need for high-precision positioners and interferometric alignment can be readily implemented in many wavelength ranges and situations.
