SBIR Phase II: Micro Pulse Lidar for Water Vapor Profiling

该小型企业创新研究(SBIR)第二阶段项目旨在满足对用于差动吸收激光雷达(DIAL)测量水蒸气的新一代激光发射器的需求。第二阶段将开发一种新的激光技术，用于水蒸气的微型刻度盘测量。Dial发射器的要求将使用一种革命性的技术来实现，该技术允许二极管棒的衍射限制性能。这些超亮二极管使端面泵浦、调Q、低增益、准三能级激光器成为可能。最近，一种直接工作在944.1纳米水蒸气吸收线上的激光材料已经商业化。将这两项技术结合起来，将产生一种高效的紧凑型拨号发射器。这项技术将产生一种用于大气水汽廓线的紧凑、高效和低成本的新型DIAL发射机。低成本DIAL发射机对于未来天气预报、全球气候模式和了解大气中通信信号的传输具有重要意义。此外，还将在医疗和材料加工行业发现潜在的商业应用。

This Small Business Innovation Research (SBIR) Phase II project addresses the need for a new generation of laser transmitters for differential absorption lidar (DIAL) measurements of water vapor. Phase II will develop a new laser technology for mini-DIAL measurements of water vapor. DIAL transmitter requirements will be achieved using a revolutionary technology that allows diffraction limited performance from diode bars. These ultra bright diode bars enable efficient end pumped, q-switched, low-gain, quasi-three level lasers. Recently, a laser material that operates directly at the 944.1 nanometer water vapor absorption line has become commercially available. Coupling these two technologies will result in an efficient compact DIAL transmitter. This technology will result in a new class of compact, efficient, and low-cost DIAL transmitters for atmospheric water vapor profiling.Low cost DIAL transmitters are important for future improvements in weather forecasting, global climate models, and understanding of the transmission of communication signals in the atmosphere. In addition, potential commercial applications will be found in the medical and material processing industries.
