A Pulsed Laser System for Experiments in Physical Chemistry

本课题是在化学本科教学实验楼内建立一个脉冲染料激光实验室。 正在购买一台Nd-YAG泵浦激光器，为三个学生染料激光站和光学混合实验提供足够的功率。 正在为初级和高级课程开发几个新的荧光/磷光光谱学、动力学和非线性光谱学实验。 特别值得注意的是，新系统使双光子吸收过程和分子振动和旋转的相干拉曼研究成为可能。 这些台站利用连接到个人计算机的数字示波器进行数据收集和分析。 本科生受益于激光和数字仪器的现代化学应用的实用实践经验。

This project is establishing a pulsed dye laser laboratory in the chemistry undergraduate teaching laboratory building. One Nd-YAG pump laser is being purchased to provide power sufficient for three student dye laser stations and for optical mixing experiments. Several new experiments in fluorescence/phosphorescence spectroscopy, kinetics, and nonlinear spectroscopy are being developed for junior and senior level courses. Of special note, the new system makes possible two-photon absorption processes and coherent Raman studies of molecular vibrations and rotations. The stations utilize digital oscilloscopes interfaced to PC's for data collection and analysis. Undergraduates benefit from useful hands-on experience in modern chemical applications of lasers and digital instrumentation.
