Acquisition of an Excimer Pumped Dye Laser System

激光发射出一束相干的、强大的、近乎单色的电磁辐射。这种辐射在化学中被用来研究广泛的学科，从蛋白质和核酸的动力学到光电子转移过程，从界面化学到皮秒脉冲整形。激光在光学、通信和工程中也很有用。这项来自化学共享仪器计划的奖项将帮助阿拉巴马大学化学系购买激光设备。该设备将用于以下研究活动：1.多烯和类胡萝卜素自由基阳离子的CIDEP研究2.有机超导体中光激发态的驰豫动力学3.非施主-西格玛-受体聚二乙炔的线性光学性质

Lasers emit a narrow beam of coherent, powerful and nearly monochromatic electromagnetic radiation. This radiation is used in chemistry to study a broad range of subjects, from the dynamics of proteins and nucleic acids to photoelectron transfer processes, and from interfacial chemistry to picosecond pulse shaping. Lasers are also useful in optics, communication, and engineering. This award from the Chemistry Shared Instrumentation Program will help the Department of Chemistry at the University of Alabama purchase laser equipment. This equipment will be used in the following research activities: 1. CIDEP Studies of Polyene and Carotenoid Radical Cations 2. Relaxation Dynamics of Photo-Excited States in Organic Superconductors 3. Non-Linear Optical Properties of Donor-Sigma-Acceptor Polydiacetylenes
