ECS-9805888博尔顿 本文报道了超快（10- 100 fs）激光非线性动力学的实验研究。 这项跨学科的工作将汇集来自两个非常活跃的领域，超快激光和混沌/非线性动力学的知识。 从事这项工作的机会是由于这两个领域的最新进展。 在超快激光器中，新系统的开发比以前的激光系统更通用，更稳定，允许精确测量以前不可能的动态。 在非线性动力学中，最近对多模态系统的理论研究使得理论与实验可以直接比较。 拟议的实验有两个主要目标。 首先，我们将把非线性动力学的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。 这种理解超快激光的新方法有可能对激光发展产生重大影响。 第二，我们希望通过在以前无法访问的政权提供精确的动力学测量非线性动力学领域作出贡献。 这项工作将在威廉姆斯学院进行，这是一个高度选择性的本科文科院校，具有浓厚的本科研究传统。 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，学生将获得广泛的研究培训激光，光学和电子，以及在开发计算机控制运行测量和分析数据。 小规模的实验允许每个学生执行完整的和有意义的项目，包括实验设计，数据采集和分析，以及理论建模。 该项目的PI目前是在她的第三年，在威廉姆斯助理教授。 在四名才华横溢的本科生的合作下，她建立了一个超快激光系统，并开始开发一系列新颖的测量技术，可以对超快激光脉冲序列的时间，光谱和空间轮廓进行全面分析。 实验室的初步结果表明，该激光系统确实提供了一个丰富的和良好控制的新的动力学模型系统。 此外，我们的测量技术的初步使用表明他们可能的成功。 然而，为了进行完整的测量与动态分析所需的精度，我们需要更先进的设备比目前在我们的实验室。 PI正在进入她的助理教授年的下半年，并在课堂和实验室中表现出显着的承诺。 一个电源补助金将提供必要的设备，用品和时间，以帮助保持PI集中在她的学术生涯。

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.
