The Combustion Diagnostics and  Environmental Measurements Laboratory

	Tunable Diode Laser Research aims to a) Develop accurate methods for calibration and use of 2f (wavelength modulation) spectroscopy at high temperatures, and b) Deploy multiplexed sensors for measurements of species concentrations and temperature in combustion systems. This project has been funded by the National Institutes of Standards and Technology and by the Office of Naval Research.
