This Small Business Innovation Research (SBIR) Phase I project will study and design a tunable infrared source. For many years, spectroscopists have depended heavily on tunable dye lasers and harmonic generators to explore molecular reactions and compounds by their characteristic spectra in the visible and ultraviolet (UV) wavelength regions. More recently, solid state parametric oscillators have become indispensible tools in the UV, visible, and near-infrared (IR). Compared to these wavelength regions, the mid-IR region of 4 to 12 microns is relatively unexplored. Although the mid-IR is rich in rotational/vibrational spectra for molecules, there are no commercial, coherent, tunable mid-IR sources available for spectroscopy. Phase I will develop this important system in a design based on pumping with an Nd:YAG laser, which is a common type of laser in spectroscopy laboratories. Phase II would build a prototype mid-IR laser with features conducive to the laboratory environment, including computer control of the device. A tunable mid-IR source would be used widely in environmental monitoring, chemical and pharmaceutical research, microelectronics manufacturing, and combustion research for the automotive and defense industries.

这个小企业创新研究（SBIR）第一阶段项目将研究和设计一个可调谐红外光源。 多年来，光谱学家一直严重依赖于可调谐染料激光器和谐波发生器，通过其在可见光和紫外（UV）波长区域的特征光谱来探索分子反应和化合物。 近年来，固态参量振荡器已成为紫外、可见光和近红外（IR）领域不可或缺的工具。 与这些波长区域相比，4至12微米的中红外区域相对未被探索。 虽然中红外线富含分子的旋转/振动光谱，但没有商业的、相干的、可调谐的中红外线源可用于光谱学。 第一阶段将开发这一重要的系统，其设计基于Nd：YAG激光器的泵浦，这是光谱实验室中常见的激光类型。 第二阶段将建立一个原型中红外激光器的功能有利于实验室环境，包括计算机控制的设备。 可调谐中红外光源将广泛用于环境监测、化学和制药研究、微电子制造以及汽车和国防工业的燃烧研究。
