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.

激光是物理科学中的多功能工具，能够 完成其他工具无法完成的任务。 的出现 廉价、易于使用和可靠的染料激光器使得有可能 在物理科学课程中引入各种实验， 本科水平。 物理系学生和 化学将使用激光和辅助检测设备， 进行各种实验，包括：测量 光在空气和液体中的速度，单光子和双光子的研究 荧光，利用拉曼散射来研究结构， 分子，并检测纳克量的有毒黄曲霉毒素 从谷物样本中。 在这个项目中开发的实验将 提供给其他学校，以扩大影响，并准备更多的 学生在物理科学的职业生涯。
