染料溶液中微微秒超荧光光谱的动力学研究

Kinetic investigations of picosecond superfluorescence spectra in dye solutions

本文介绍采用时间分辨的频率上转换法研究染料溶液中微微秒超荧光光谱动力学过程的装置和实验结果.实验研究了超荧光的脉宽压缩,荧光中心波长的位移和增益带宽对泵浦光参量以及染料溶液浓度的依赖关系.

An experimental setup of time resolved frequency up-conversion exployed for studying picosecond superfluoresoence (SF) spectra kinetics processes in dye solutions was reported and the experimental results was given in this paper. The dependence of the SF pulse width compression, the shift of the SF centre wavelength and the gain band on pump pulse parameters and dye concentrations were studied experimentally.
