Imaging of the spatial distribution of atoms in a laser-produced plasma with one-dimensional coherent hyper-Raman scattering in wide-aperture beams Academic Article uri icon


  • An experimental technique based on coherent one-dimensional four-wave mixing with hyper-Raman resonances has been developed for line-by-line imaging of excited atoms in a low-temperature plasma of optical breakdown. The technique was used to visualize the spatial distribution of excited lead atoms in a plasma of optical breakdown produced on a metal target. The technique of line-by-line plasma imaging was compared with the four-photon technique of point-by-point measurements. The estimates of the spatial resolution of the technique under study are presented and the potentialities of its application to plasma diagnostics are discussed.
