Paper Abstract

A polarization property of a laser output was characterized for a CO2 laser with a mirror of anisotropic reflectivity for p and s polarization installed within the cavity. A slight difference of reflectivity of the mirror for p and s polarization is emphasized through the multiple reflection within the laser cavity, because a laser system forms a feedback system to reach a laser oscillation. By using this idea of feedback system, a laser output with a linear polarization of a large polarization ratio and with a specially polarized mode like TE01 which has a polarization vector tangential to a circle was obtained. A new type of measuring system is proposed to measure the polarization characteristics of the reflectivity of a mirror like sample set within a laser cavity through a laser output.
