Abstract
Results are presented of the development and study of metal vapors active elements using an induction heater, which is designed to create a required metal vapor concentration. The lasing was obtained at traditional (GDT with internal electrodes) and capacitive (capacitive barrier discharge) excitation of the laser medium; the average laser power was 20 mW. For the Cu-vapor active element under capacitive excitation, two generation pulses with a time delay of 50 ns were detected. Thus, within the limits of a single pump pulse, the lasing was obtained with a frequency of 20 MHz.
