Experimental Atomic and Molecular Physics Via Laser Induced Fluorescence and Laser Optogalvanic Spectroscopy

基于使用可调谐染料激光器作为探测光源的气体和等离子体的主动光学光谱技术，正在为三门高级物理课程开发一系列动手实验室练习。这些实验室为学生提供操作和校准染料激光系统的实践经验，并教授我们在物质光谱研究中使用扫描窄带染料激光的各种方法。目前正在初步开发四个核心练习，并逐步扩展和增加额外的练习，作为由物理专业高年级学生进行的独立研究项目。以下是最初的四个核心练习：(1)染料激光和校准简介；(2)用激光光电流光谱学研究原子结构；(3)用激光诱导荧光和激光吸收光谱学研究分子结构；(4)等离子体中静电波的光学诊断。重点是学生的实际参与和充分利用当前最先进的主动光谱分析仪器和程序，如频率扫描、窄带染料激光和用于信号分析的辅助光学元件和仪器。

A series of hands-on laboratory exercises are being developed for a triad of upper-division physics courses based on the techniques of active optical spectroscopy of gases and plasmas using a tunable dye laser as probing light source. The laboratories give students hands-on experience in operating and calibrating a dye laser system and teach various ways in which we can use scanning, narrowband dye lasers in the spectroscopic study of matter. Four core exercises are being developed initially, with gradual extensions and additional exercises being added as independent research projects conducted by senior physics majors. The following form the initial four core exercises: (1) An Introduction to Dye Lasers and Calibration; (2) Investigation of Atomic Structure by Laser Optogalvanic Spectroscopy; (3) Spectroscopic Study of Molecular Structure by Laser Induced Fluorescence and by Laser Absorption; and (4) Optical Diagnosis of Electrostatic Waves in Plasma. Emphasis is placed on hands-on student participation and the full utilization of current state-of-the- art active spectroscopy apparatus and procedures as provided by frequency scanning, narrowband dye lasers and supporting optical components and instrumentation for signal analysis.
