面向超快二维电子光谱的脉冲压缩技术
Pulse compression technology for ultrafast two-dimensional electronic spectroscopy
摘要
Abstract
Pulse compression is one of the key technologies in ultrafast 2DES(two-dimensional electronic spectroscopy),which determines the time resolution of the system and is of great significance for studying ultrafast dynamic such as excited-state relaxation,solvation,and quantum coherent energy transfer.A systematic review of commonly-used pulse compression methods in 2DES was provided.The time-frequency characteristics of femtosecond laser pulses were introduced.Then,the principles and limitations of various pulse compression techniques were discussed in detail,including grating pairs,prism pairs,grating-prism combinations,pulse shapers,and chirped mirror pairs.By examining representative cases,the selection strategies for compression methods in different 2DES systems were analyzed.Through a systematic review of different pulse compression methods in 2DES,aimed to facilitate the development of advanced domestically mastered ultrafast spectroscopic instruments and contribute to the advancement of ultrafast science and related interdisciplinary fields.关键词
