Industrial CO2 laser with the phase compensation of the high-order cavity mode

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