提案编号：0521037提案标题：通过拉曼放大和压缩开发一种新型的高功率超短脉冲激光器PI名称：Szymon SuckewerPI机构：普林斯顿大学智力优点：这笔赠款将资助PI购买1.9焦耳的TI/蓝宝石放大器，这是开发小型高频激光器所需的大型设备的关键部件，其发射的光脉冲短于50飞秒，能量约为0.5焦耳。PI计划将大学研究中可用的能量密度提高一个数量级或更多。然后，新激光器将被应用于普林斯顿大学在光驱动化学处理、量子计算和更高功率台式X射线激光方面的研究。自适应反馈控制将是使整个系统真正工作的关键因素。更广泛的影响：最重要的更广泛的影响是这项技术本身的潜在影响。如果仪器开发成功，PI和主要零部件供应商之间的合作伙伴关系可能会导致这种仪器在世界各地广泛获得和使用。光驱动化学加工是一个重要的新兴领域，在许多领域都有潜力，如先进、更高效的燃料加工。这里的基础技术--拉曼背向散射增强光--的发展可能会提高激光诱导核聚变的经济性或可行性，这种能源可能会填补未来全球经济中的一个关键漏洞。这种设备还将支持普林斯顿大学的跨学科教育--包括研究生和本科生。

Proposal Number: 0521037Proposal Title: Development of a New Type of High Power, Ultrashort Pulse Laser via Raman Amplification and CompressionPI Name: Szymon SuckewerPI Institution: Princeton University Intellectual Merit: This grant will fund the PI to buy a 1.9 joule TI/sapphire amplifier, the key piece of large equipment needed to develop a small-scale high-frequency laser which emits pulses of light shorter than 50 femtoseconds with energy of about half a joule. The PI plans to increase the energy density available in university research by an order of magnitude or more. The new laser will then be applied to research at Princeton in light-driven chemical processing, in quantum computing, and in higher-power table-top X-ray lasers. Adaptive feedback control will be a crucial element in making the overall system actually work. Broader Impact: The most important broader impact is the potential impact of this technology as such. If the instrument development is successful, partnership between the PI and the primary component supplier will probably result in making such instruments widely available and used across the world. Light-driven chemical processing is an important emerging area, with potential in many areas, such as advanced, more efficient fuel processing. Development of the underlying technology here - light enhancement by Raman backscattering - might improve the economics or feasibility of laser-induced nuclear fusion, an energy source that could fill a crucial hole in the future global economy. This equipment will also support crossdisciplinary education - both graduate and undergraduate - at Princeton.
