| Abstract: | Ultrafast spectroscopy has drawn great interest recently.Among its advantages are ultrahigh time resolution,wide-ranging nonlinear light-matter interactions,coherent control of quantum states,and the possibility of developing many related technologies.We describe its general principles and the technical realization of time-resolved measurements,including the typical geometries.The significance of ultrafast spectroscopy in the study of condensed matter physics is illustrated through various examples. |
