Development of a novel laser source for nonlinear optical applications EArly-concept Grant for Exploratory Research

在这个早期概念的探索性研究资助（EAGER），由化学系的化学测量和成像计划资助，来自密歇根州立大学的Marcos Dantus教授将研究一种新的方法来设计和建造飞秒激光器。拟议的发展旨在利用电信半导体泵浦CW激光器的稳定性和低成本来产生超短脉冲。由此产生的激光器应该模仿传统超快激光器的能力，但具有更大的稳定性，坚固性，效率和成本低于目前可用的来源。该源将采用Dantus开发的自适应脉冲压缩技术。这种新光源的成功演示将使其在生物医学成像、传感、计量和通信领域得到应用。新的源应该是理想的便携式传感仪器的坚固，紧凑，节能的组件。非线性光学成像和传感应用将被用来展示由此产生的新技术的实际能力。拟议的低成本方法将使超快激光器（主要用于时间分辨光谱和非线性光学成像）可用于更广泛的研究实验室，并通过增加对该技术的可及性和依赖性来促进科学发现。

In this EArly-concept Grant for Exploratory Research (EAGER), funded by the Chemical Measurement and Imaging Program of the Division of Chemistry, Professor Marcos Dantus from Michigan State University will investigate a novel approach to the design and construction of femtosecond lasers. The proposed development seeks to exploit the stability and low cost of the telecommunication semiconductor pumped CW lasers to generate ultrashort pulses. The resulting laser should mimic the capabilities of a traditional ultrafast laser, but have greater stability, ruggedness, efficiency and lower cost than the presently available sources. The source will incorporate adaptive pulse compression technology developed by Dantus. The successful demonstration of this new source will lead to its use in the areas of biomedical imaging, sensing, metrology and communications. The new source should be ideal for portable sensing instrumentation given the rugged, compact, and energy efficient components. Nonlinear optical imaging and sensing applications will be used to demonstrate the practical capabilities of the resulting new technology. The proposed low-cost approach will make ultrafast lasers (primarily used for time-resolved spectroscopy and for nonlinear optical imaging) available to a much wider variety of research laboratories, and boost scientific discovery by increased accessibility and reliance of this technology.
