The hybrid femtosecond/picosecond coherent anti-Stokes Raman scattering (fs/ps CARS)
technique presents a promising alternative to either fs time-resolved or ps frequency …

A hybrid fs/ps pure-rotational coherent anti-Stokes Raman scattering (CARS) scheme is
systematically evaluated over a wide range of flame conditions in the product gases of two …

High-repetition-rate, single-laser-shot measurements are important for the investigation of
unsteady flows where temperature and species concentrations can vary significantly. Here …

Gaining information of species, temperature, and velocity distributions in turbulent
combustion and high-speed reactive flows is challenging, particularly for conducting …

Two-dimensional gas-phase coherent anti-Stokes Raman scattering (2D-CARS)
