00899807GlebovThis three-year award for U.S.-France cooperative research in optical materials for high-power lasers involves Leonid B. Glebov and Oleg M. Efrimov of the University of Central Florida and Dr. Laurent Sarger of the Unviersity of Bordeaux I and the Center for Molecular, Optical and Oscillation Physics. The proposal addresses problems related to the selffocusing of laser beams that result in damage to the laser's optical components. One of the most important parameters of optical materials used in multi-channel laser systems is the nonlinear refractive index (n2), which drives the selffocusing process. Materials, which have low n2 values, such as fused silica, may reduce damage duringlaser beam transport and focusing. In this collaboration the investigators will compare the nonlinear refractive index for samples of fused silica fabricated with different technologies and the linear optical and spectral properties of the samples. They will also determine the features of linear and nonlinear optical properties fluctuations. The project takes advantage of US and French complementary expertise in the fields of linear and nonlinear optical properties, laser-induced breakdown, structure, and technology of silicate glasses. The joint efforts will advance understanding of the principle of high quality fused silica selection for optical components in multi-channel high-power laser systems. This award represents the US side of a joint proposal to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover the expenses of visits of US investigators. The CNRS will support the visits of French researchers to the United States.

00899807格列波夫美国-法国高功率激光器光学材料合作研究涉及Leonid B。Glebov和Oleg M.中佛罗里达大学的Efrimov和波尔多第一大学的Laurent Sarger博士以及分子、光学和振荡物理中心。 该提案解决了与激光束的自聚焦有关的问题，这些问题导致激光器的光学部件损坏。 在多通道激光系统中使用的光学材料的最重要的参数之一是非线性折射率（n2），其驱动自聚焦过程。 具有低n2值的材料，如熔融石英，可以减少激光束传输和聚焦过程中的损坏。在这次合作中，研究人员将比较用不同技术制造的熔融石英样品的非线性折射率以及样品的线性光学和光谱特性。它们还将决定线性和非线性光学性质波动的特征。 该项目利用了美国和法国在硅酸盐玻璃的线性和非线性光学特性、激光诱导击穿、结构和技术领域的互补专业知识。 双方的共同努力将促进对多通道高功率激光系统中光学元件的高质量熔融石英选择原则的理解。该奖项代表了美国方面向NSF和法国国家科学研究中心（CNRS）提出的联合建议。 NSF将支付美国调查人员的访问费用。CNRS将支持法国研究人员访问美国。
