Narrative: A pulsed laser system presently available at Cornell                 (Quanta-Ray DCR-2) is upgraded to include a third harmonic                      generator, a dye oscillator/amplifier, and a doubling crystal.                  The resulting pulses of tunable coherent light enable                           measurements of (1) velocities in dense gas-solid flows and (2)                 radical species concentrations in the reaction zone of premixed                 turbulent flames.                                                                                                                                               In dense gas-solid flows, the pulsed dye laser enables particle                 and gas velocity measurements using a fiber-optic time-of-flight                anemometer probe.  At the probe tip, laser-induced-                             phosphorescence is detected to infer velocity of a tracer gas or                specially coated particles.  This new diagnostic will provide                   detailed information on gas-solid flow patterns in fluidized                    beds.                                                                                                                                                           In premixed turbulent flame combustion, fluorescence of radical                 species induced by the tunable dye laser provides unique data on                the structure of strained flamelets.
