*9760821 Vujkovic-Cvijin这个小型企业创新研究第一阶段项目将开发一种基于中红外(2-5.5微米)二极管的激光光源，用于大气光谱和遥感，无需低温制冷。该仪器是基于III-V二极管激光器的近红外辐射频率转换而来的。介绍了一种提高输出功率的新方法。在第一阶段，仪器将进行更高的频率转换测试。在第二阶段期间，将建造一个优化的源，并为生产准备一个工作样机。在室温下工作在中红外区域的小型窄带激光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医疗诊断、工业过程控制和环境监测中得到商业应用。***

*** 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. ***
