Laser Spectroscopy Equipment for an Undergraduate Chemistry Laboratory

该项目的目标是组装多功能激光光谱仪的基本部件，使物理化学专业的学生能够进行拉曼光谱、时间分辨吸收光谱和时间分辨荧光光谱的实验。整个系统包括脉冲Nd：YAG激光器和染料激光器，以及用于存储和分析数据的单色仪、信号处理器和实验室计算机。光谱仪将被用来向学生介绍几种现象和技术，这些现象和技术对当前的化学研究很重要。这些课程包括(A)激光的原理和应用，(B)测量非常快的过程的技术，(C)复杂的光电系统的操作，以及(D)计算机接口和实验控制。该系统还将为化学专业的学生提供使用最先进的激光设备进行独立研究项目的机会。这个项目的一个重要成果将是最终出版各种经过良好测试的、有文件记录的实验，供使用最先进的激光系统的本科生使用。因此，该项目可以作为全国的示范，并为提高国家一级的化学教育做出贡献。

The goal of this project is to assemble the essential components of a versatile laser spectrometer to enable students of physical chemistry to carry out experiments in Raman spectroscopy, time-resolved absorption spectroscopy, and time-resolved fluorescence spectroscopy. The total system includes both a pulsed Nd:YAG laser and a dye laser, as well as a monochromator, a signal processor, and a laboratory computer to store and analyze the data. The spectrometer will be used to introduce students to several phenomena and techniques which are important to current research in chemistry. These include (a) principles and applications of lasers, (b) techniques for measuring very fast processes, (c) manipulation of a sophisticated optical-electronic system, and (d) computer interfacing and control of experiments. This system will also provide an opportunity for chemistry majors to use state-of-the art laser equipment for independent research projects. An important outcome of this project will be the eventual publication of a variety of well-tested, documented experiments for undergraduates using state-of-the-art laser systems. Thus this project can serve as a national model, and contribute to the improvement of chemistry education on the national level.
