Abstract

The spectrum has been calculated numerically of the radiation from aluminum plasma produced by a moderate-power CO2 laser. These calculations and experiments with the pulsed CO2 laser show that the main part of the thermal plasma radiation falls at photons with energy more than 11 eV. It is shown for the first time that, upon exposure of the target to the CO2-laser radiation, the efficiency of the conversion of the laser energy into that of the thermal plasma radiation is higher than in the case of a neodymium laser under the same conditions, and amounts to about 30-50%.
