飞秒时间分辨实验中泵浦-探测交叉相关函数的测量和时间零点的确定
Determine The Pump-probe Cross Correlation Function and The Zero of Time of The Pump and Probe Laser in Femtosecond Time-resolved Studies
摘要
Abstract
Femtosecond laser technique,not only makes the observation of excited state relaxation processes more directly,but also offers information for disentangle the complex dynamics of excited state relaxation processes.However,what have an explosive impact on accuracy and reliability of experimental result is that cross correlation function as well as the zero of time of the pump and probe laser pulses,therefore,determine the correct value of them is the most vital process in the experiment.Examples of applying the femtosecond pump-probe technique is presented to study the relaxation dynamics of the molecular excited states,by what,on the basis of experimental conditions and requirements,the paper introduced approaches of determine the cross correlation function as well as the zero of time of the pump and probe laser pulse in the course of concrete femtosecond time-resolved experiments.For the pump and the probe laser pulses in the visible light range,by way of delay time of the pump and the probe pulses,we could apply optical technique to detect the transient of the intensity of the second harmonic generation.Yet,for the determination of correlation function as well as the zero of time for the ultrafast pulses in the UV or the VUV,calibration method would be an ideal method.关键词
