An Undergraduate Laboratory in Atomic, Molecular and OpticalSpectroscopy

原子、分子和光学(AMO)物理是本科生物理实验经验的重要组成部分。AMO物理学与当前研究的许多其他领域相比具有优势，无论是理论上还是实验上都是本科生可以接触到的。该项目的目标是在该领域建立一个本科实验室。为了发展一个强大的AMO物理本科实验室项目，使用了几件基础设备和辅助硬件。第一个主要设备是一米单色计，这是一种在经典光谱学中有无数用途的设备。它被用来向学生介绍经典的光谱测量。其次，使用了两种激光系统，一种是基于脉冲激光系统的脉冲激光系统，该激光系统是基于激光泵浦的染料激光器；另一种是用于现代原子和分子光谱学的连续波半导体激光器。学生可以研究脉冲光谱学和连续波光谱学，以确定时间和频率域之间的基本关系。光谱学设备为学生提供机会学习实验的一般原理，并向他们介绍特定的原子现象。

Atomic, molecular, and optical (AMO) physics is an important part of the undergraduate physics laboratory experience. AMO physics has the advantage over many other fields of current research of being accessible to undergraduates both theoretically and experimentally. The objective of the program here is to establish an undergraduate laboratory in this field.To develop a strong undergraduate laboratory program in AMO physics, several pieces of capital equipment and ancillary hardware are used. The first major piece of equipment is a one-meter monochrometer, a device with innumerable uses in classical spectroscopy. It is used to introduce students to classical spectroscopic measurements. Second, two laser systems are used, one a pulsed laser system based on Nd:YAG pumped dye lasers, and the other a continuous wave semiconductor diode laser for use in modern atomic and molecular spectroscopy. Students can investigate both pulsed and cw spectroscopy to determine the fundamental relationship between the time and frequency domains.The spectroscopy equipment provides students with an opportunity to learn general principles of experimentation as well as introduce them to specific atomic phenomena.
