SBIR Phase I: Programmable Tunable Single Frequency Ytterbium Laser

这个小企业创新研究第一阶段项目将生产具有TEMoo模式的窄线宽，单频，可调谐Yb激光器。这样的激光器将是一个非常有用的工具，许多重要的应用，如光参量振荡器（opo）和光纤放大器的泵浦源。初步分析表明，基于腔内电磁场空间结构的新技术是满足该激光器要求的最佳途径。这种方法允许可伸缩性和多功能性，同时在相对简单和稳定的配置中仍然实现出色的性能。所提出的系统应在单个纵向模式下产生数百兆瓦的功率，具有宽调谐范围和窄带宽下优异的频率稳定性。所开发的系统将从根本上改善可调谐激光器的特性，并将成为光谱学、参数振荡器、时钟等移动“各方”之间高数据传输速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.
