摘要
Ultrafast optics is an interdisciplinary research area as the interface between physics,optics,photonics,chemistry and engineering.Currently,the cutting-edge research interests in this area include,but are not limited to,the development of frontier ultrafast lasers and their applications in photophysics,quantum science,nonlinear optics,light–matter interaction,and ultrafast dynamics.This special issue is a collection of selective research articles focusing on ultrafast laser sources,ultrafast imaging technique,and ultrafast dynamics in molecules and solid-state materials.Ongoing with this special issue,Chinese Optics Letters aims to continuously offer an active platform for communications on the latest progress in the field of ultrafast optics.
