0079774迪金森该奖项是为收购一个可调谐，超快激光设施，以扩大现有的能力，在材料物理和化学研究在华盛顿州立大学（WSU）。 该仪器将由来自WSU的八名生产教师，他们的学生和他们的博士后研究员使用，他们都在先进材料研究领域工作。 爱达荷州大学的另一名研究人员也将使用该仪器。 新仪器提供了一个完整的，多功能的光源，范围在脉冲持续时间从皮秒下降到100飞秒在波长范围从250纳米（5电子伏）到3毫米（0.4电子伏）。光子能量和脉冲宽度的这些广泛变化对材料研究具有相当大的意义，因为它使科学家能够探测许多现代和模型材料的基础和激发电子结构。 受益于这种仪器的研究包括努力了解应用于薄膜合成和化学分析的激光解吸和烧蚀，激光损伤和表面改性，基本激光表面相互作用，非线性光谱研究，波导，腔和散装材料中的非线性传播，聚合物光纤中的超快全光开关，以及与实验工作直接相关的理论研究。该奖项是为了获得一个可调谐的超快激光设备，以扩展华盛顿州立大学在材料物理和化学研究方面的现有能力。 该仪器将由WSU的八名生产者，他们的学生和他们在先进材料研究领域工作的博士后研究员使用。 来自爱达荷州大学的一位科学家也将使用该设备。 新仪器将提供一个完整的、多功能的光源，其脉冲持续时间范围从80皮秒到100飞秒，光谱范围从紫外到红外。 受益于这种仪器的研究包括努力了解应用于薄膜合成和化学分析的激光解吸和烧蚀，激光损伤和表面改性，基本激光表面相互作用，非线性光谱研究，波导，腔和散装材料中的非线性传播，聚合物光纤中的超快全光开关，以及与这些实验直接相关的理论研究。

0079774DickinsonThis award is for the acquisition of a tunable, ultrafast laser facility to extend existing capabilities in materials physics and chemistry research at Washington State University (WSU). The instrumentation will be used by eight productive faculty from WSU, their students, and their postdoctoral fellows who are all working in areas of advanced materials research. The instrument will also be used by one additional researcher from the University of Idaho. The new instrument provides a complete, versatile light source that ranges in pulse duration from picoseconds down to 100 femtoseconds over a wavelength range from 250 nanometer (5 electron volts) to 3 mm (0.4 electron volts). These wide variations in photon energy and pulse width are of considerable interest for materials research because it allows scientists to probe both ground and excited electronic structure of many modern and model materials. Research benefiting from this instrumentation includes efforts to understand laser desorption and ablation as applied to thin-film synthesis and chemical analysis, laser damage and surface modification, fundamental laser-surface interactions, nonlinear spectroscopic studies, and nonlinear propagation in waveguides, cavities, and bulk materials, ultrafast all-optical switching in polymer optical fibers, and theoretical studies that relate directly to the experimental efforts.This award is for the acquisition of a tunable, ultrafast laser facility to extend existing capabilities in materials physics and chemistry research at the Washington State University.
