Quantitative one-dimensional single-pulse temperature measurements by broadband N(2) vibrational coherent anti-Stokes Raman scattering (CARS) are presented. A planar BOXCARS phase-matching geometry was used to generate the CARS signal along a 6.16-mm path positioned perpendicularly to the beam propagation. Depending on the imaging optics used, a spatial resolution of 86 mm was achieved. The applicability of this technique for measuring temperature gradients is demonstrated in a premixed laminar CH(4) -air f lame.
