Tunable diode laser absorption spectroscopy (TDLAS) is proving to be a valuable tool for monitoring chemical species in combustion environments. TDLAS is being used to characterize low pressure, premixed methane/oxygen/argon flames inhibited with candidate Halon replacement agents and Halon 130(CF{sub 3}Br). Species concentration profiles are measured spectroscopically by either direct absorption or derivative spectroscopy. Species temperature profiles are measured spectroscopically using Two-Line Thermometry, and flame temperature is measured with fine wire thermocouples. The results of recent studies using the diode laser technique are discussed.
