Spatially and spectrally resolved multipoint coherent anti-Stokes Raman scattering from N_2 and O_2 flows

Single-shot spectrally resolved broadband rotational coherent anti-Stokes Raman scattering (CARS) from multiple points along a line intersecting a flow has been observed for N(2) and O(2). A large-angle phase-matching configuration was used to achieve spatial resolution of 0.1 mm x 0.1 mm x 0.1 mm for each of 20 points in the interactionvolume. Single-shot multipoint CARS of N(2) at different temperatures and of several species in a coflowing jet was observed.
