中文摘要
提出了超快(10-100fs)区域非线性激光动力学的实验研究。这项跨学科的工作将汇集两个非常活跃的领域的知识,超快激光和混沌/非线性动力学。由于这两个领域的最新进展,有机会从事这项工作。在超快激光器中,新系统的发展既更加通用,又比以前的激光系统稳定几个数量级,从而可以精确测量以前不可能实现的动力学。在非线性动力学中,最近关于多模态系统的理论工作允许直接将实验与理论进行比较。拟议中的实验有两个主要目标。首先,我们将非线性动力学技术应用于超快激光器,这是一个具有广泛技术重要性的高度非线性系统。这种理解超快激光器的新方法有可能对激光的发展产生重大影响。其次,我们希望通过在以前无法进入的状态下提供精确的动力学测量来为非线性动力学领域做出贡献。这项工作将在威廉姆斯学院进行,这是一所具有很强本科研究传统的高选择性本科文科院校。所有提出的实验都将以本科生为中心进行。通过参与这项研究,学生将在激光,光学和电子学方面获得广泛的研究培训,以及开发用于运行测量和分析数据的计算机控制。小规模的实验允许每个学生完成完整而有意义的项目,包括实验设计,数据采集和分析,以及理论建模。该项目的PI目前是她在威廉姆斯大学担任助理教授的第三年。她与四名优秀的本科生合作,建立了一个超快激光系统,并开始开发一系列新的测量技术,可以对超快激光脉冲序列的时间,光谱和空间特征进行全面分析。实验室初步结果表明,该激光系统确实提供了一个丰富的、可控的新动力学模型系统。此外,最初使用我们的测量技术表明他们可能成功。然而,为了完成动力学分析所需的精确测量,我们需要比我们实验室目前可用的更先进的设备。这位PI进入了她助理教授生涯的下半年,并在课堂和实验室中显示出了巨大的希望。power补助金将提供必要的设备,用品和时间,以帮助保持PI专注于她的学术生涯。
英文摘要
ECS-9805888 Bolton An experimental study of nonlinear laser dynamics in the ultrafast (10-100fs) regime is proposed. This cross disciplinary work will bring together knowledge from two very active fields, ultrafast lasers and chaos/nonlinear dynamics. The opportunity to pursue this work arises due to recent advances in both fields. In ultrafast lasers, the development of new systems which are both more versatile and orders of magnitude more stable than previous laser systems allows precise measurements of dynamics that were not previously possible. In nonlinear dynamics, recent theoretical work on systems with many modes allows direct comparison of experiment with theory. The proposed experiments have two main goals. First, we will apply the techniques of nonlinear dynamics to ultrafast lasers, a highly nonlinear system with wide ranging technological importance. This new approach to understanding ultrafast lasers has the potential to make a substantial impact on laser development. Second, we hope to contribute to the field of nonlinear dynamics by providing precise dynamical measurements in a previously inaccessible regime. This work will be performed at Williams College, a highly selective undergraduate liberal arts institution with a strong tradition of undergraduate research. All of the experiments proposed will be carried out with undergraduate students in a central role. By participating in this research, students will receive a broad research training in lasers, optics and electronics, as well as in developing computer control for running measurements and analyzing data. The small scale of the experiments allows each student to perform complete and meaningful projects, including experimental design, data acquisition and analysis, and theoretical modeling. The PI for this project is currently in her third year as an assistant Professor at Williams. With the collaboration of four talented undergraduates, she has built an ultrafast laser system and started the developme nt of a series of novel measurement techniques which allow full analysis of the temporal, spectral, and spatial profiles of ultrafast laser pulse trains. Preliminary results obtained in the lab indicate that the laser system indeed provides a rich and well controlled new dynamical model system. Furthermore, initial use of our measurement techniques indicates their likely success. However, in order to perform complete measurements with the precision necessary for dynamical analysis, we require more advanced equipment than is currently available in our lab. The PI is entering the second half of her assistant professor years, and has shown significant promise in the classroom and in the laboratory. A POWRE grant will provide the essential equipment , supplies and time to help keep The PI focused in her academic career.
