Rapid-Tuning Infrared Laser System
Abstract
We propose to acquire a rapid-wavelength-tunable, continuous-wave, narrow-linewidthexternal-cavity quantum cascade laser system to enable the measurement of the fullfundamental rovibrational absorption band of nitric oxide (NO) in high-temperature andhigh-pressure conditions. We are currently able to measure the fundamental rovibrationalband of NO over a limited set of wavelengths at moderate wavelength-tuning rates and theacquisition of this laser system will enable the creation of a comprehensive high-temperatureand high-pressure spectral database that will increase the range of applicability of NOabsorption sensing to infer the temperature of high-enthalpy flows in practical ground-testfacilities needed to evaluate new propulsion concepts.This equipment will also be used in the training and education of the next generation ofgraduate students in mechanical engineering in the areas of interest to the Air Force:hypersonics, laser diagnostics, and shock tube methods.
