Nonlinear-optical imaging and tagging of atoms and molecules in plasmas and gas flows Conference Paper uri icon

abstract

  • The possibilities of two nonlinear-optical techniques for plasma imaging and flow tagging are discussed taking into account distortions of two-dimensional four wave mixing (FWM) maps of plasma species due to phase mismatch and one-photon absorption. The implemented experimental technique for imaging the relative populations of excited states of atoms in a decaying low-temperature plasma of optical breakdown induced on the surface of a metal target is based on three-color coherent FWM with hyper-Raman resonances. The implemented technique was applied to map the spatial distributions of excited lead and nitrogen atoms in a laser plasma produced on the surface of a lead target in ambient air.
