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.

原子、分子和光学（AMO）物理是本科物理实验室经验的重要组成部分。相对于当前许多其他研究领域，AMO物理学在理论和实验上都对本科生开放。这个项目的目标是在这个领域建立一个本科实验室。为了建立一个强大的AMO物理本科实验项目，使用了一些基本设备和辅助硬件。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。它是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Nd:YAG泵浦染料激光器的脉冲激光系统，另一种是用于现代原子和分子光谱学的连续波半导体二极管激光器。学生可以研究脉冲和连续波光谱，以确定时域和频域之间的基本关系。光谱学设备为学生提供了学习实验的一般原理以及介绍特定原子现象的机会。
