An enhancement of an advanced laboratory course in modern physics for physics majors is proposed. The specific goal is to offer new experiments closely related to present-day research and applications in the areas of atomic physics and condensed matter, in response to a projected increase of students with interests in applied and engineering physics. The project introduces to the laboratory two new experiments: one using a solid state diode laser to do optical pumping and spectroscopy of atoms in an atomic beam and a second experiment involving measurements on a high Tc superconductor. The laser spectroscopy is combined with a Stern-Gerlach experiment to yield a rich variety of atomic physics effects which would be accessible to the undergraduate student. In addition to the Stern-Gerlach effect, the experiment allows demonstrations of: Doppler-free optical spectroscopy, hyperfine structure, optical pumping, radio frequency resonance, and Zeeman effect. The experiment on a high Tc superconductor involves measurements of the persistent current.

提出了对物理专业的现代物理学高级实验室课程的增强。 具体的目标是提供与当今的研究以及原子理和凝结物质领域的应用密切相关的新实验，以响应对应用和工程物理学兴趣的学生的预计增加。 该项目向实验室介绍了两个新实验：一个使用固态二极管激光器在原子束中对原子进行光学泵送和光谱，第二次实验涉及高TC超导体上的测量。 激光光谱法与船尾 - grach实验相结合，以产生各种各样的原子物理效应，这些效应可供本科生访问。 除了船尾 - gerlach效应外，该实验还允许演示：无多普勒光学光谱，超细结构，光学泵送，射频共振和Zeeman效应。 高TC超导体上的实验涉及持续电流的测量。
