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 …

Spatio-temporally resolved measurements of temperature using hybrid femtosecond/
picosecond rotational coherent anti-Stokes Raman scattering (fs/ps RCARS) are evaluated …

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

This manuscript describes the wide variety of optical measurement techniques for
characterizing the flow in hypersonic wind tunnels. The introduction briefly describes …
