A Nd:YAG Pumped Dye Laser for the Undergraduate Laboratories

该项目支持该系在本科生化学课程中使用激光泵浦的染料激光器和相关的电子设备。将脉冲可调谐激光引入教学和研究实验室，反映了物理化学和无机化学的当代研究活动。新的仪器仪表对高师教学和实验课产生了重大影响。从物理化学序列的光谱学实验室开始，学生学习激光和调谐、信号采集、数据采集和仪器与计算机接口的基础知识。然后，他们将这一技术应用于收集霓虹和氩气的吸收光谱。在这个实验的基础上，学生们测量和分配菲的单光子和双光子吸收光谱。在高级无机实验室中，学生使用该设备研究通过金属蛋白的远程电子转移动力学。在这里，他们学习瞬变吸收和发射光谱的基本原理。此外，激光系统可能会在两个本科研究实验室广泛使用，一个专注于无机光化学，另一个专注于材料研究。

This project supports the department's use of a Nd:YAG-pumped dye laser and the associated electronics equipment in the undergraduate chemistry program. Incorporation of a pulsed, tunable laser into the teaching and research laboratories reflects contemporary research activities in physical and inorganic chemistry. The new instrumentation has a major impact on the upper-division teaching and laboratory courses. Beginning with the spectroscopy laboratory of the physical chemistry sequence, students learn the basics of lasing and tuning, collecting signals, data acquisition, and instrument-to-computer interfacing. They then apply this know-how to collecting the absorption spectra of Neon and Argon. Building on this experiment, students measure and assign the one- and two-photon absorption spectra of phenanthrene. In the senior-level inorganic laboratory, students use the equipment to investigate the long-range electron-transfer kinetics through metalloproteins. Here, they learn the fundamentals of transient absorption and emission spectroscopy. Additionally, the laser system may be used extensively in two undergraduate research laboratories, one that focuses on inorganic photochemistry and the other, on materials research.
