Development of new two-pulse correlation technique for observation and analysis of multiphoton reaction

在本研究中，两个实验技术，即非对称双脉冲相关（as-2 PC）技术，通过多光子/多步激发过程理解激发/反应动力学和傅里叶变换二维激发光谱（FT-2DES）测量系统，澄清激发/反应路径，被开发。 后者是傅里叶变换双脉冲相关法的基础系统。 然后将AS-2 PC方法与FT-2DES系统相结合，提出了一种新的观测和分析技术，用于理解激发/反应途径。 特别地，在FT-2DES测量系统中，通过使用串联型法布里-珀罗干涉仪对激发光进行调制，成功地增加了调制深度。

In the present study, two experimental techniques, namely asymmetric two-pulse correlation (as-2PC) technique for understanding excitation/reaction dynamics through multiphoton/multistep excitation process and Fourier transform two-dimensional excitation spectrum (FT-2DES) measurement system for clarify the excitation/reaction paths, were developed. The latter is the basis system of Fourier transform two-pulse correlation method. Then by combining the as-2PC method and the FT-2DES system, new observation and analysis technique for understanding the excitation/reaction pathways. In particular, in the FT-2DES measurement system, the increase of modulation depth was succeeded by using the tandem type Fabry-Perot interferometer to a modulation of the excitation light.
