This Small Business Innovation Research (SBIR) Phase I project will lead to the development of compact, low cost gas sensors and analyzers based on cavity ringdown spectroscopy using near-infrared lasers manufactured for fiber optic communications. Although conventional cavity ringdown spectroscopy can achieve part per trillion detection limits for many gases (water vapor, carbon dioxide, ammonia), few commercial applications require such extraordinary sensitivity. Instead, price and reliability are controlling factors for the sensors and analyzers market. That is why we propose a modified form of ringdown spectroscopy that should lead to low cost, compact, and rugged instruments. The Phase I effort is designed to demonstrate the effectiveness of our proposed technique which will lead to the development of a prototype instrument in Phase II.Commercial applications include industrial process analysis and control, bioreactor monitoring, and worker safety. Ideally, the sensors and analyzers will be low power (possibly battery operated), self-calibrating and self-checking devices that will be sufficiently rugged to allow in situ installation.

该小型企业创新研究（SBIR）第一阶段项目将开发基于腔衰荡光谱的紧凑型、低成本气体传感器和分析仪，使用为光纤通信制造的近红外激光器。虽然传统的光腔衰荡光谱可以达到万亿分之一的检测极限，许多气体（水蒸气，二氧化碳，氨），很少有商业应用需要这种非凡的灵敏度。相反，价格和可靠性是传感器和分析仪市场的控制因素。这就是为什么我们提出了一种改进形式的衰荡光谱，应该导致低成本，紧凑，坚固的仪器。第一阶段的努力是为了证明我们提出的技术，这将导致在第二阶段的原型仪器的发展的有效性。商业应用包括工业过程分析和控制，生物反应器监测，和工人的安全。理想情况下，传感器和分析仪将是低功率（可能是电池供电）、自校准和自检设备，这些设备将足够坚固，以允许现场安装。
