US-France Cooperative Research: High-and Ultrahigh-Intensity CPA Lasers and Their Applications

0351023 Mourou随着激光峰值功率增加到极高的水平，激光与物质的相互作用将需要在时间和空间上最干净的脉冲。这些先进的激光器是必要的，以便在一个新的强度制度的实验可以在尽可能高的强度水平进行，没有任何预先形成的等离子体。 在美国-法国合作研究项目由密歇根大学物理前沿中心的Gerard Mourou和Ecole Polytechnique's Optoire d 'Optique Queries（LOA）的Daniele胡林领导，目标是产生具有最高时间对比度的最高强度激光。 他们建议开发一种脉冲清洁器，使产生峰值与背景对比度大于10^10/1的脉冲成为可能。 一个在密歇根大学，另一个在法国LOA的博士后研究人员将研究解决这个问题的不同方法。 这项为期一年的赠款和法国国家科学研究中心的类似资金为博士后研究员的交流提供了支持。拟议的研究将对超高强度社区产生广泛影响。目前，由于缺乏脉冲的时间和空间质量，无法完成尽可能高强度的实验。 拟议的合作研究项目如果成功，可能导致开发一种新的高强度激光器（1000太瓦）。

0351023MourouAs laser peak power increases to extremely high levels, laser-matter interaction will demand the cleanest pulses both in time and in space. These advanced lasers are necessary for so that experiments in a new intensity regime can be performed at the highest intensity level possible, without any preformed plasma. In this U.S.-France cooperative research project led by Gerard Mourou of the University of Michigan's Physics Frontier Center and Daniele Hulin at the Ecole Polytechnique's Laboratoire d'Optique Appliquee (LOA) the objective is to produce the highest intensity laser with the highest temporal contrast. They propose to develop a pulse cleaner that will make possible the generation of pulses with a peak to background contrast greater than 10^10/1. Postdoctoral researchers, one at the University of Michigan and another at LOA in France will work on different approaches to the problem. This one-year grant and comparable funding from the French National Center for Scientific Research provides support for this exchange of postdoctoral research fellows. The proposed research will have broad impact on the ultra-high intensity community. Presently experiments at the highest intensity possible cannot be accomplished because of the lack of temporal and spatial quality of the pulses. The proposed cooperative research project, if successful, could lead to development of a new, high intensity laser (1000 Terrawatts).
