Abstract

Internal field correction elements of the waveguide laser resonator on the basis of statistically homogeneous and periodic structures which can be used for enhancement of operation of CO₂ waveguide laser is studied. A diffraction model that can incorporate the effect of light scattering by waveguide wall for typical experimental conditions is formulated. Resonator is divided into a number of longitudinal segments to obtain required precision. Optical losses for eigenmodes of such system (eigenvalues of the round-trip propagation operator) have been investigated for different parameters of the waveguide resonator. A direct comparison between theoretical losses behavior and experimentally measured ones demonstrated a satisfactory agreement for various conditions.
