摘要
本文对噁嗪(Oxagine)、甲酚紫(cresyl violet)染料分子的吸收带和吸收边进行了非相干光时延四波混频(TDFWM-IL)的详细研究,得到了有关失相参量的数据,并利用非相干光时延四渡混频的多能理论解释了实验结果和失相参量的物理意义。
In this paper time-delayed four-wave mixing with incoherent light is applied for the study of vibratlonal dephasing processes of some dye molecules in excited electronic states. The information on subpicosecond dephasing time in absorption band of oxagine in PMMA and in solution, and in absorption edge of cresyl violet in PMMA has been obtained. A detailed physical interpretation of the observed dephasing time is given on the basis of our multi-level theory of time-delayed four-wave mixing with incoherent light.
