0958790Romanowski"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."This proposal describes acquisition of a broadly tunable femtosecond laser system, which includes an optical parametric oscillator pumped by a titanium-sapphire laser and associated instrumentation. It will enable a broad range of experimental work on the interface of nanotechnology, materials sciences and medicine. This highly advanced instrumentation is prohibitively expensive to be acquired through individual research funding. The requested instrument will be installed in a novel type of a laser beam facility, which will provide open access to the laser beam, and room for multiple experimental installations as required by researchers sharing the research focus on optical spectroscopy and imaging. Research in many areas of chemistry, materials sciences, biology and medicine relies on using light for probing structure and function of individual molecules, their assemblies, and living systems. Increasingly important is understanding of photophysics and photochemistry at the time scale as short as femtoseconds, and in the broad spectral range spanning ultraviolet, visible and near infrared. The shared laser facility is requested by a core user base representing a broad range of research expertise and active projects. When installed, it will accelerate the pace of research in medical diagnosis and intervention, analytical methods for bio-threat agents, solar energy harvesting and conversion, and basic sciences.

0958790Romanowski“该奖项是根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金的。”该提案描述了购买广泛可调的飞秒激光系统，其中包括由钛蓝宝石激光器泵浦的光学参量振荡器和相关仪器。它将促进纳米技术、材料科学和医学交叉领域的广泛实验工作。这种高度先进的仪器通过个人研究经费购买的价格极其昂贵。所需的仪器将安装在一种新型激光束设施中，该设施将提供激光束的开放通道，并根据共同研究光谱和成像的研究人员的要求，为多个实验装置提供空间。化学、材料科学、生物学和医学许多领域的研究依赖于利用光来探测单个分子、其组装体和生命系统的结构和功能。在短至飞秒的时间尺度以及跨越紫外线、可见光和近红外线的宽光谱范围内了解光物理学和光化学变得越来越重要。代表广泛研究专业知识和活跃项目的核心用户群要求共享激光设施。安装后，它将加快医学诊断和干预、生物威胁因子分析方法、太阳能收集和转换以及基础科学方面的研究步伐。
