Abstract

Measurements of CO and NO are reported using room-temperature, mid-IR quantum cascade lasers operating at 4.6 μ and 5.26 μ, 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.
