Development of an Undergraduate Laser Spectroscopy Course

化学系将购买一台氦氖激光器 在本科生实验室里。 激光实验课 理科大三、大四光谱学 将得到发展。 本课程的目标是让学生 更详细地研究某一专题的机会 同时，在科学课程中， 提供愉快的实验室体验。 该课程是 分为三个部分。 第一部分将涉及 使用氦氖激光器与收集的光学 元件来研究激光的特性。 还 将解释激光作用的化学过程。 在 第二部分，学生将探索两种类型的 激光光谱仪，连续波系统使用氩气 离子激光源和使用氮泵浦的脉冲系统 染料激光器 在最后一节中，学生们分成小组， 将得到一个或两个项目，将利用 高于激光系统。 这些项目将涉及解决一个 而不是遵循食谱程序。 的 这种方法的目的是鼓励学生思考 创造性地与其他学生互动， 问题

The Department of Chemistry will purchase a HE Ne laser for use in the undergraduate laboratory. A laboratory course in laser spectroscopy for undergraduate junior and senior science majors will be developed. The goal of this course is to give students the opportunity to study a special topic in more detail than is possible in their science courses and, at the same time, to provide an enjoyable laboratory experience. The course is divided into three sections. The first section will involve the use of a He Ne laser with a collection of optical components to study the properties of laser light. Also, the chemical processes of lasing action will be explained. In the second section, students will explore the uses of two types of laser spectrometers, a continuous-wave system using an argon ion laser source and a pulsed system using a nitrogen-pumped dye laser. In the last section, students, in small groups, will be given one or two projects which will make use of the above laser systems. The projects will involve solving a stated problem rather than following a cookbook procedure. The object of this approach is to encourage students to think creatively and to interact with other students in solving problems.
