Paper Abstract

Results of studies of an EB-controlled discharge in a pulse-periodic CO2 laser are given. A conclusion on the expediency of the change in the traditional transverse scheme of the gas mixture circulation through the discharge region for the longitudinal one is reached. It is shown that a laser with the longitudinal circulation scheme offers a 1.5-fold efficiency over that of a laser with the transverse scheme and a 1.8-times higher beam brightness on the polar diagram axis in the far field. Based on the obtained data, an experimental prototype of the technological CO2 laser providing an average output power of more than 10 kW in the pulse-periodic mode at the beam divergency of not more than 0.42 mrad is constructed.
