Abstract

Most of the serial internal-mirror gas lasers have nonpolarized output radiation. Such a fact causes an amplitude unstability and loss of energy if an optical scheme with a laser designed for a determined polarization. Polarizers, inserted into a laser resonator (Brewster plates, prisms, etc.), complicate its construction and increase losses. Laser resonator design is significantly simplified by the use of laser mirrors having a noticeable polarization anisotropy of reflectance for two orthogonal polarizations.
