Abstract

The experimental results on efficient coherent harmonic generation and four-wave Raman and hyper-Raman scattering in a laser-produced and electric discharge plasma are presented. It has been shown that in the four-wave mixing processes, spectra resonances appear due to the Raman and hyper-Raman scattering on atomic and ionic excited states. The temporal behavior of the scattered signal has been found to be connected with the population relaxation of atomic and ionic excited states. We have observed for the first time the resonance in the spectrum of coherent hyper-Raman scattering in electric discharge plasma connected with the electron transition from the excited to autoionizing state of a copper atom.
