Abstract

Correction of static-resonator misalignment errors in a CO₂ laser has been obtained through the use of an intracavity deformable-mirror adaptive-optical system. Correction of the near-field intensity distribution has been observed, accompanied by total-power increases of a factor of 2. Restoration of the far-field beam quality has been demonstrated, yielding far-field peak-intensity increases of a factor of 11.
