Purchase of Nd: YAG Pumped Dye Laser for Spectroscopic Studies

这份来自化学研究仪器项目的合同将允许美国大学化学系购买Nd:YAG泵浦染料激光器。初级教员Charles D. Pibel将是该仪器的主要用户，这将使他能够进行三态分子的腔衰落激光吸收光谱（CRLAS）研究，并探测分子的排列和取向。该激光器还将用于本科物理化学实验室，作为介绍激光基础和光谱学的教学工具。激光是在化学研究中有许多用途的光源。它们可以在实验中用于了解分子结构和不稳定自由基，并检查对材料科学和生物学具有重要影响的详细分子特性。激光也可以作为教育工具，在本科教学实验室中有效地发挥作用。

This award from the Chemistry Research Instrumentation Program will allow the Chemistry Department at American University to purchase a Nd:YAG pumped dye laser. Junior faculty member Charles D. Pibel will be the primary user of this instrument, which will allow him to perform cavity ringdown laser absorption spectroscopy (CRLAS) studies of a triplet state molecule, and to probe molecular alignment and orientation. The laser will also be used in an undergraduate physical chemistry laboratory as a teaching tool to introduce laser fundamentals and spectroscopy. Lasers are light sources that have many uses in chemistry research. They can be used in experiments to learn about the structure of molecules and unstable free radicals, and to examine detailed molecular properties that can have important ramifications for materials science and biology. Also serving as educational tools, lasers can perform effectively as instruments in undergraduate teaching laboratories.
