SBIR Phase I: High-Power Widely Tunable Middle Infrared Solid-State Laser Source for Applied Spectroscopy and Remote Sensing

该小企业创新研究（SBIR）一期项目将开发用于大气光谱和遥感的中红外（2-5.5微米）二极管激光源，该激光源无需低温冷却。该仪器是基于频率转换的近红外辐射的III-V二极管激光器进一步在红外。介绍了一种提高输出功率的新方法。在第一阶段，仪器将进行频率转换测试。在第二阶段，将建立一个优化的源，并为生产准备一个工作原型。在室温下工作的中红外区域的微型窄带激光源将主要用作光学痕量气体传感器的辐射源。基于这种来源的传感器将在商业上应用于医疗诊断、工业过程控制和环境监测。＊＊＊

*** 9760821 Vujkovic-Cvijin This Small Business Innovation Research (SBIR) Phase I project will develop a mid-infrared (2-5.5 micron) diode-based laser source for atmospheric spectroscopy and remote sensing, which operates without cryogenic cooling. The instrument is based on the frequency conversion of near infrared radiation of III-V diode lasers further in the infrared. A novel approach to increase the output power is described. In Phase I the instrument will be tested with increased frequency conversion. During Phase II an optimized source would be built, and a working prototype prepared for production. The miniature, narrowband laser source operating at room temperature in the mid-infrared region will be used a primarily as the radiation source for optical trace gas sensors. Sensors based on this source will be commercially applicable in medical diagnostics, industrial process control, and environmental monitoring. ***
