An account is given of recent progress in the development of nonintrusive optical diagnostic techniques and the application of these techniques to turbulent combustion systems. The primary focus of the work over the past year has been in: (1) the use of a broadband rotational coherent anti-Stokes Raman scattering (CARS) technique for the measurement of temperature in flames, (2) the use of broadband rotational N/sub 2/ CARS from many spatially resolved volume elements along a cylindrical line in air, and (3) the development of a technique to significantly increase the effective frame rate of our existing camera from approx. 30 frames/s to more than 2000 frames/s. A summary of new results in each of these areas is given.
