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.

化学系将购置一台氦氖激光器供本科生实验室使用。为本科、大三、大四理科生开设激光光谱学实验课程。本课程的目标是让学生有机会比他们的科学课程更详细地研究一个特殊的主题，同时提供一个愉快的实验室体验。课程分为三个部分。第一部分将涉及使用氦氖激光器与光学元件的集合来研究激光的性质。此外，还将解释激光作用的化学过程。在第二部分中，学生将探索两种类型激光光谱仪的使用，一种是使用氩离子激光源的连续波系统，另一种是使用氮泵浦染料激光器的脉冲系统。在最后一节，学生将以小组为单位，分配一到两个使用上述激光系统的项目。这些项目将涉及解决一个既定的问题，而不是遵循一个食谱程序。这种方法的目的是鼓励学生创造性地思考，并在解决问题时与其他学生互动。
