Shawn Wehe, David Sonnenfroh, Mark Allen, Claire Gmachl, Federico Capasso, "Quantum-Cascade Laser-Based Sensor for CO and NO Measurmenets in Combustor Exhaust Flows," presented at 37th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit (Salt Lake City, Utah) , (8-11 July2001).
AbstractMeasurements of CO and NO are reported using room-temperature, mid-IR quantum cascade lasers operating at 4.6 µm and 5.26 µm, respectively. Using a balanced ratiometric detection technique, sensitivities on the order of 10 ppbv are achieved for each species. Extensions to in-situ, high-temperature measurements for combustion control applications are described. Keywords,sr-1068
