Research of Condensed Matter Physics based on Ultrafast Spectroscopy

摘要

Ultrafast spectroscopy has many characteristics, which has attracted much attention in recent years. It is of high time resolution, rich nonlinear interaction of light and matter. It can be used to regulate the quantum state of matter coherent photons and its derivatives and grafting technology bring a lot of changes in condensed matter physics experiment technology. This article introduces the general principles time-resolved technique and typical configuration of ultrafast spectroscopy. Through specific examples this paper shows its applications in condensed matter physics research.
