This project is upgrading an existing one-semester Modern Physics Laboratory into a two-semester Junior Physics Laboratory through the development of new experiments in laser spectroscopy and modern optics.Physics majors at Trinity receive an excellent introduction to experimental physics. We have established a first-rate lower-division laboratory sequence, including an exceptional program on the use of computers in physics. However, we are convinced that students at Trinity and many of its peer institutions do not obtain sufficient experience with the advanced experimental techniques employed in today's research laboratories. We are therefore introducing revisions in our curriculum, including a required Senior Thesis research project, to bring students much closer to the research capabilities of contemporary physics. By placing a very high priority on modern experimental techniques, we intend to attract a much larger number of talented majors interested in careers in advanced physics research, and to prepare these majors for study in highly competitive graduate programs.The laboratory improvements defined in this proposal is providing the capstone of our new emphasis on contemporary experimental methods. We are taking advantage of the wide range of advanced experimental topics that can be investigated using moderate-cost lasers, and the high level of student interest in laser-based experiments. A nitrogen-pumped dye- laser system, a Fabry-Perot spectrometer, and Macintosh computer systems are the major apparatus that have been purchased for the experiments. These equipment items are quite versatile; most are being used in more than one investigation. The laser-based experiments proposed here can thus serve as models for the next generation of upper-division physics laboratories.

该项目通过开发激光光谱和现代光学的新实验，将现有的一个学期现代物理实验室升级为两学期的初级物理实验室。三位一体的Physics Majors在实验物理学方面获得了极好的介绍。 我们已经建立了一流的下级实验室序列，包括有关物理中计算机使用的杰出程序。 但是，我们坚信三位一体及其许多同伴机构的学生在当今研究实验室中使用的先进实验技术没有足够的经验。 因此，我们在课程中介绍了修订，包括所需的高级论文研究项目，以使学生更接近当代物理学的研究能力。 通过对现代实验技术进行高度重视，我们打算吸引更多对高级物理学研究职业感兴趣的才华横溢的专业，并为这些专业的研究生准备这些专业的研究生。正在提供我们对当代实验方法的新重点的顶峰。 我们正在利用可以使用中等成本激光器以及学生对基于激光的实验的高度兴趣来研究的广泛的高级实验主题。 氮气泵染色器系统，Fabry-Perot光谱仪和Macintosh计算机系统是用于实验的主要设备。这些设备物品用途广泛。大多数都用于多次调查。 因此，此处提出的基于激光的实验可以作为下一代上级物理实验室的模型。
