Your library or personal account may give you access

Abstract

A hybrid rotational CARS scheme with femtosecond pump/Stokes preparation and a high-energy probe, generated by second-harmonic bandwidth compression (SHBC), is described. The instrument is demonstrated for collision- and background-free, kHz-rate temperature/oxygen probing in the product gases of C2H4/air flat flames for both lean and rich conditions.
