Abstract

ABSTRACT The need to measure high repetition rate ultrafast processes cuts across multiple areas of science. The last decade has seen tremendous advances in the development and application of new techniques in this field, as well as many breakthrough achievements analyzing non-repetitive optical phenomena. Several approaches now provide convenient access to single-shot optical waveform characterization, including the dispersive Fourier transform (DFT) and time-lens techniques, which yield real-time ultrafast characterization in the spectral and temporal domains, respectively. These complementary approaches have already proven to be highly successful to gain insight into numerous optical phenomena including the emergence of extreme events and characterizing the complexity of laser evolution dynamics. However, beyond the study of these fundamental processes, real-time measurements have also been driven by particular applications ranging from spectroscopy to velocimetry, while shedding new light in areas spanning ultrafast imaging, metrology or even quantum science. Here, we review a number of landmark results obtained using DFT-based technologies, including several recent advances and key selected applications. GraphicalAbstract

时间拉伸色散傅立叶变换及其应用研究进展

摘要测量高重复率超快过程的需求涉及多个科学领域。在过去的十年里，该领域新技术的发展和应用取得了巨大进展，在分析非重复光学现象方面也取得了许多突破性成果。现在有几种方法提供了对单次光学波形表征的方便访问，包括色散傅立叶变换（DFT）和时间透镜技术，它们分别在光谱域和时域中产生实时超快表征。这些互补的方法已经被证明是非常成功的，可以深入了解许多光学现象，包括极端事件的出现和表征激光进化动力学的复杂性。然而，除了对这些基本过程的研究之外，实时测量还受到从光谱学到测速技术等特定应用的驱动，同时在超快成像、计量学甚至量子科学领域也有了新的发展。在这里，我们回顾了使用基于DFT的技术获得的一些具有里程碑意义的结果，包括一些最新进展和关键的选定应用。图形摘要

期刊介绍： Advances in Physics: X is a fully open-access journal that promotes the centrality of physics and physical measurement to modern science and technology. Advances in Physics: X aims to demonstrate the interconnectivity of physics, meaning the intellectual relationships that exist between one branch of physics and another, as well as the influence of physics across (hence the “X”) traditional boundaries into other disciplines including: Chemistry Materials Science Engineering Biology Medicine
