项目摘要

This proposal aims to develop and implement a new "track-based" advanced physics laboratory course, where students undertake a series of related experiments in a single area of physics. The experiments in a given track begin simply, and expand into greater levels of sophistication as the course progresses. Although the experiments themselves cover only one area, the experimental techniques used apply to many other areas of physics. A comprehensive tutorial is to accompany and describe the experiments, providing the necessary background and motivation for the laboratory investigations. It is believed that such a track-based lab course is more effective than traditional physics laboratory courses at teaching students experimental physics, and at instilling in students a higher level of confidence and competence in the laboratory.Two tracks will be created: 1) laser-based atomic/molecular/optical physics, and 2) acoustics. The first track makes use of new and significant advances in semiconductor diode laser technology. Applying recently-developed techniques, visible 670-nm diode lasers are being made into tunable narrow- linewidth laser light sources, which emit at the wavelength of the D-lines of lithium. Using these laser tools, fundamental phenomena in atomic and optical physics are being demonstrated. The second track explores several aspects of classical and modern acoustics, with special attention paid to recent advances in quantum and non-linear acoustics.

这项建议旨在制定和实施一个新的“轨道为基础的” 高级物理实验室课程，学生在那里进行在物理学的一个单一领域中的一系列相关实验。的在给定轨道上的实验开始很简单，然后扩展到随着课程的进展，会有更高层次的复杂性。虽然实验本身只涉及一个领域，所使用的实验技术适用于许多其他领域，物理学一个全面的教程是陪同和描述实验，提供必要的背景和实验室调查的动机。据信这种基于轨道的实验室课程比传统物理实验课的教学实验物理，并在灌输给学生更高的实验室的信心和能力水平。将创建：1）基于激光的原子/分子/光学物理学和2）声学。第一条轨道利用新的半导体二极管激光器的重大进展技术. 应用最近开发的技术，可见 670纳米二极管激光器正被制成可调谐窄，线宽激光光源，其发射波长为锂的D线使用这些激光工具，原子物理和光学物理中的现象正在被证明。第二条轨道探讨了古典和现代声学，特别注意最近量子和非线性声学的进展。
