Coherent four-photon spectroscopy of excited atoms in a laser-produced plasma: From point-by-point to multipoint two-dimensional mapping
An experimental technique for the two-dimensional mapping of the relative populations of excited states of atoms and ions in a low-temperature plasma of optical breakdown is developed on the basis of coherent four-wave mixing (FWM) with hyper-Raman resonances. Conditions when FWM in a plasma occurs...
