Abstract

Improvements introduced in a gas discharge laser that has reflectors (laser mirrors) connected near the two ends of the part of the discharge tube that forms the laser tube, in which the beam of light coming out of the discharge laser in gas is linearly polarized by application of a transverse magnetic field whose direction is substantially normal to the axis of the laser tube, said magnetic field being generated by a magnet arranged near the laser tube, characterized in that two anisotropic reflectors are used in phase ( double refraction), substantially coinciding the directions of the anisotropic axes of the two reflectors or essentially at right angles to each other, the direction of the magnetic field coinciding substantially with one of the anisotropic axes of the reflectors.
