Implementation of Raman and Other Modern Spectroscopies in the Upper-Level Physics Undergraduate Laboratories

现代分子光谱学和微观分析实验最近在UCF(am.J.Phys.62,429-434(1994))将被引入中级和高级本科实验室。本科生正在学习微拉曼光谱表征材料等技能，这将为他们准备研究生或进入就业市场提供有用的知识。他们正在利用过去十年该领域发生的技术革命，使小型、低成本、高通量的仪器成为可能。这些实验非常适合本科课程，因为它们允许学生研究基本的物理现象以及许多有用的应用。该实验室配备了一台使用固体激光激励的拉曼光谱仪和一个显微镜附件。在中级实验室中，学生将亲身体验使用多通道检测的吸收、发射和荧光。高级实验室的实验主要集中在拉曼光谱和材料的微观分析上。选择激光晶体和金刚石薄膜作为例子说明了物理学可以应用于相关专题问题的方法。新的仪器也被用于本科生的研究项目和演示。这使学生能够研究当前材料光谱学中的概念。作为这一项目的结果，学生们对光谱仪器有了更好的理解，并将在佛罗里达州中部地区正在发展的大型激光和光电行业中获得高度的就业机会。

Modern molecular spectroscopy and micro-analysis experiments recently developed at UCF (Am. J. Phys. 62, 429-434 (1994)) will be introduced into the intermediate and advanced undergraduate laboratories. Undergraduate students are learning skills such as materials characterization by micro-Raman spectroscopy which will give them useful knowledge in preparing them for graduate school or entering the job market. They are taking advantage of the technological revolution that has taken place in this field during the past decade making small, low-cost, high-throughput instruments possible. These experiments fit very well into the undergraduate curriculum since they allow the students to investigate basic physics phenomena as well as many useful applications. The laboratory is equipped with a Raman spectrometer employing solid state laser excitation and a microscope attachment. In the intermediate lab the students have hands-on experience with absorption, emission and fluorescence using multichannel detection. Experiments in the advanced laboratory focus on Raman spectroscopy and microanalysis of materials. The choice of laser crystals and diamond films as examples illustrate ways that physics can be applied to relevant topical issues. The new instrumentation are also being used in undergraduate research projects and demonstrations. This allows students to investigate concepts in current materials spectroscopy. As a result of this program students have an improved understanding of spectroscopic instrumentation and should become highly employable in the large laser and electro-optics industry that is evolving in the Central Florida region.
