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

一系列的动手实验练习正在为高级物理课程开发，其基础是气体和等离子体的主动光谱学技术，使用可调谐染料激光器作为探测光源。实验室为学生提供操作和校准染料激光系统的实践经验，并教授各种方法，我们可以在物质的光谱研究中使用扫描，窄带染料激光器。初步形成四个核心习题，并逐步扩展和增加额外的习题，作为物理专业高年级学生的独立研究项目。以下是最初的四个核心练习：(1)染料激光器和校准介绍；(2)激光光电光谱法研究原子结构；(3)激光诱导荧光和激光吸收光谱法研究分子结构；(4)等离子体静电波的光学诊断。重点放在学生的实际参与和充分利用当前最先进的主动光谱设备和程序，如提供的频率扫描，窄带染料激光器和支持光学元件和仪器的信号分析。

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.
