INFRARED RADIATION IN CO2:N2:He ACOUSTOPLASMA

Abstract

Modulation of the discharge current by a sinusoidal law in a discharge tube excites an acoustic field and plasma transferred to acoustoplasma state. It is shown, that parameters of the acoustoplasma significantly differ from the parameters of the unperturbed plasma. For the discharge tube of a CO2 laser, operating in an acoustoplasma state, experimentally have been shown power- current characteristics and the Fourier spectra of laser pulses at 10.6 microns. The same time, the results of experiment show, that in acoustoplasma all the defining parameters of the plasma strongly depend on the components of a mixture of gases in the discharge, frequency and modulation depth of the discharge current.
