Abstract
Theoretical propositions of powerful technological CO2 laser operation with selection and correction of phase of high order cross models have been experimentally studied. The effective transformation with the help of phase corrector of the high order mode oscillations field to the narrow directed beam at the level of output power up to 1kW is reported for the first time. The physical nature of intra-cavity aberrations with negative influence on the beam quality is analyzed. It is shown that the most significant aberrations such as optical wedge arise when we use the cross pumping of active medium and the cross discharge. The prospect of the considered method application to obtain narrow directed radiation is considered at higher power values.
