The Addition of Laser Techniques to Advanced Laboratories in Physics and Chemistry

激光是自然科学中的多功能工具，能够完成其他工具无法完成的任务。廉价、易用和可靠的染料激光器的出现使在本科生水平的物理科学课程中引入各种实验成为可能。物理系和化学系的学生将使用激光和辅助检测设备进行各种实验，包括：测量空气和液体中的光速，研究单光子和双光子荧光，利用拉曼散射研究分子结构，以及从谷物样品中检测亚纳克量的有毒黄曲霉毒素。这个项目中开发的实验将提供给其他学校，以扩大影响，并为更多的学生在物理科学领域的职业生涯做好准备。

Lasers are versatile tools in the physical sciences that are able to accomplish tasks that no other tool can achieve. The advent of inexpensive, easy-to-use and reliable dye lasers makes it possible to introduce a variety of experiments into physical science programs at the undergraduate level. Students in the Departments of Physics and Chemistry will use the lasers and auxiliary detection equipment to perform a variety of experiments including: the measurement of the speed of light in air and liquids, studies of one and two photon fluorescence, the use of Raman scattering to study the structure of molecules, and the detection of subnanogram amounts of toxic aflatoxins from grain samples. The experiments developed in this project will be made available to other schools to extend the impact, and prepare more students for careers in the physical sciences.
