9523193 Stanton This research is to improve infrared (IR) lasers to make them more reliable for field application and provide adequate wavelength coverage. A compact, diode pumped wavelength modulatable mid-IR solid state laser will be developed, targeted toward development of rugged instruments for ultrasensitive detection of trace chemical species. This fiber laser will operate in the 2.7 micron region for trace species detection using wavelength modulation absorption spectroscopy. The resulting IR laser will be applicable to a wide range of industrial processes. These processes include process and stack gas monitoring, plasma process control, gas impurity monitoring, and real-time monitoring of tailpipe emissions.

小行星9523193 本研究旨在改进红外（IR）激光器，使其在现场应用中更可靠，并提供足够的波长覆盖范围。 一个紧凑的，二极管泵浦的波长可调制的中红外固态激光器将被开发，目标是发展坚固耐用的仪器，用于超灵敏检测痕量化学物质。 该光纤激光器将在2.7微米区域工作，用于使用波长调制吸收光谱法进行痕量物质检测。 由此产生的红外激光器将适用于广泛的工业过程。 这些过程包括工艺和烟道气监测、等离子体工艺控制、气体杂质监测和尾气排放实时监测。
