Abstract
In terms of Collins' formuJa, the diffraction integral equations for a piano-concave resonator are presented and transformed to the finite-sum matrix equations. The mode-field distributions and losses of a common piano-concave resonator and that with a Gaussian-reflectivity mirror are calculated. It is shown that the Gaussian-reflectivity piano-concave resonator has good choosing capability for transverse modes, which can be employed in the transverse-flow high-power CO2 laser to improve quality of laser beam.
