This Small Business Innovation Research (SBIR) Phase I project will develop a new, electronically tunable laser source, capable of emitting narrowband emission in the mid-infrared (IR) region - from 2 microns to approximately 4 microns. Purely electronic tuning and high efficiency of difference frequency generation in a nonlinear crystal will be achieved by use of a specially designed acousto-optic tunable filter. The filter serves two purposes: selecting two lasing wavelengths simultaneously generated inside the cavity and controlling the cavity gain for each of those wavelengths. The gain control will ensure optimum pulse energies and pulse synchronization for efficient generation of mid-IR emission in a nonlinear KTiOPO4 (KTP) crystal. Development of this tunable laser for the mid-IR spectral region will enlarge the areas of application of laser spectroscopy and greatly increase the ability of differential absorption lidar techniques to detect atmospheric contaminants. Such applications include, but are not limited to, remote atmospheric sensing and other environmental monitoring.

该小型企业创新研究（SBIR）第一阶段项目将开发一种新的电子可调谐激光源，能够在中红外（IR）区域发射窄带发射-从2微米到约4微米。 采用特殊设计的声光可调谐滤波器，可实现非线性晶体的高效率差频产生和电子调谐。 滤波器有两个目的：选择腔内同时产生的两个激光波长，并控制每个波长的腔增益。 增益控制将确保最佳的脉冲能量和脉冲同步，用于在非线性KTiOPO 4（KTP）晶体中有效地产生中红外发射。 这种可调谐激光器的中红外光谱区域的发展将扩大激光光谱学的应用领域，并大大提高差分吸收激光雷达技术检测大气污染物的能力。 这些应用包括但不限于大气遥感和其他环境监测。
