Purchase of an UV-IR Picosecond Laser Facility

激光发出一束相干的、强大的、近乎单色的电磁辐射。这束强的相干可见光和红外光将光学谐振器的原子激发到更高的能级，而谐振器迫使被激发的原子同相辐射。激光在光学、通信和工程中很有用。这项来自化学共享仪器项目的奖项将帮助普林斯顿大学化学系购买激光设备。该设备将用于以下研究活动：a)用于激光选择化学的高功率脉冲整形B)c团簇分子束中的光解离和分子弛豫分子内能流随时间变化的研究d)蛋白质和金属卟啉的结构和动力学E)仿生多血红素组合的结构和动力学f)电极上的快速反应G)DNA中的运动动力学

Lasers emit a narrow beam of coherent, powerful and nearly monochromatic electromagntic radiation. This intense beam of coherent visible and infrared light excites the atoms of the optical resonator to a higher energy level and the resonator forces the excited atoms to radiate in phase. Lasers are useful in optics, communication, and engineering. This award from the Chemistry Shared Instrumentation Program will help the Department of Chemistry at Princeton University purchase laser equipment. This equipment will be used in the following research activities: a) High Power Pulse Shaping for Laser Selective Chemistry b) Photodissociation and Molecular Relaxation in Molecular Beams of Clusters c) Time-dependent Study of Intramolecular Energy Flows d) Structural and Dynamics in Proteins and Metalloporphyrins e) Structure and Dynamics of Biomimetic Multiheme Assemblies f) Fast Reactions at Electrodes g) Motional Dynamics in DNA
