分子是组成物质的基本单位，揭示分子内部的动态演化过程是理解宏观物理机制、实现有效调控不可或缺的手段。在超快激光技术和符合探测技术飞速发展的驱动下，人们获得了观测分子内部超快动力学过程的有力工具。技术的不断革新将分子超快动力学的研究推向新的科学前沿。

Molecules are the basic unit of materials. Revealing the dynamic process inside molecules is an indispensable means to understand macroscopic physical mechanisms and achieve effective manipulation. The rapid development of ultra fast laser technology and coincident detection method allow us to observe the ultrafast dynamics inside molecules. The continuous innovation of technology has pushed the research of molecular ultrafast dynamics to a new frontier.
