SBIR Phase I: Programmable Tunable Single Frequency Ytterbium Laser

这个小型企业创新研究第一阶段项目将生产一种具有TEMoo模式的窄线宽、单频、可调的Yb激光器。这种激光器将是一种非常有用的工具，用于许多重要的应用，如用于光学参量振荡器(OPO)和光纤放大器的泵浦源。我们的初步分析表明，满足这种激光器要求的最好方法是通过一种基于腔内电磁场空间结构的新技术。这种方法允许可伸缩性和通用性，同时仍然在相对简单和稳定的配置中获得优异的性能。该系统单模输出功率可达数百mW，调谐范围宽，在窄带宽内具有良好的频率稳定度。所开发的系统将从根本上改善可调谐激光器的特性，并将成为用于光谱学、参数振荡器、时钟等移动的“各方”之间高数据传输率通信系统的理想来源。

This Small Business Innovative Research Phase I Project will produce a narrow linewidth, single frequency, tunable Yb laser having a TEMoo mode. Such a laser would be an extremely useful tool for a number of important applications, such as a pump source for optical parametric oscillators (OPOs) and fiber amplifiers. Our preliminary analysis indicates that the best way to meet the requirements for this laser is through a novel technique based on the spatial structure of the intra-cavity electromagnetic fields. This method allows for scalability and versatility, while still achieving excellent performance in a relatively simple and stable configuration. The proposed system should produce hundreds of mW of power in a single longitudinal mode, with a wide tuning range and excellent frequency stability in a narrow bandwidth. The developed system will radically improve the characteristics of tunable lasers and will be an ideal source for high data transfer rate communication system between moving 'parties' for spectroscopy, parametric oscillators, clocks and others.
