Abstract：
Tunable diode laser absorption is a powerful yet relatively simple diagnostic strategy for probing combustion flows, with the potential to measure a range of parameters including temperature, pressure, velocity and concentrations of species that absorb light in the visible to mid-infrared spectral region accessible with current tunable diode lasers.  The method applies to small molecular species, such as water vapor, CO, NO and CO2, with discrete spectral features, as well as larger species, such as hydrocarbons, with broad spectral features.  This presentation will provide a brief introduction to the fundamentals of tunable diode laser absorption, followed by four example applications: 1. Shock tube measurements of temperature and species; 2. Coal-fired power plant measurements of CO and NO; 3. Coal gasifier measurements of temperature, H2O, CO, CO2 and lower heatingvalue; and 4. Internal combustion engine measurements of gasoline. Some comments will be made about future opportunities.
