泵浦探测法测量染料分子基态恢复时间的研究

Study of ground state recovery times of dyes

本文对泵浦探测法测量染料分子基态恢复时间进行了分析,对以往的结论作了修正。提出用锁模脉冲串激发获得单个脉冲测量结果的方法。测量了BDN染料在不同溶剂中的基态恢复时间。

In this paper, the measurement on the ground state recovery time of dye by pump and probe method is analysed and the conclusions obtained previously are modified. A new method is presented by which the single pulse measurement result is obtained from the mode-looked pulss train, and the ground state recovery times of BDN dye in different solvents are measured.
