Abstract

Dielectric phase-anisotropic laser mirrors have been proposed for a two-frequency gas laser with orthogonal linear-polarized modes. Under normal light incidence the reflection phase (but not reflection amplitude) of the mirrors depends on light polarization. The mirrors consist of dielectric multilayer and anisotropic elements. One or several dielectric layers with surface- relief diffraction gratings of small period d < (lambda) have been proposed as the anisotropic element. Results of numerical and experimental investigations of the mirrors are presented. Two-frequency oscillation with up to 5 MHz frequency difference have been obtained in a gas laser with internal mirrors.
