Abstract

Formation of the given intensity distributions of fundamental mode by means of intracavity controlled mirror is discussed. Such mirror is a water-cooled bimorph flexible one having four controlling electrodes. Analysis has confirmed the possibility to form doughnut-like and super- gaussian intensity distributions at the output of the stable resonators of industrial CW CO₂ lasers. Results of experimental formation of the super-gaussian fundamental modes of the 4th and 6th orders by means of the intracavity flexible mirror are presented. The increase of power up to 12% and the enlarging of the peak value of the far-field intensity in 1.6 times in the comparison with the traditional gaussian TEM₀₀ mode of the same resonator are observed.
