Paper Abstract

Results concerning the polarization state measurements of the beam emitted by an industrial cw CO2 transverse-flow laser workin at 1.2kW are reported in the paper. A measurement procedure with a rotating analyser and a quarter-phase retarder, designed for a CO2 laser radiation is applied . The measurements prove that the optical beam transport system modifies the polarization ofthe laser radiation by increasing its ellipticity. The investigations of the temporal stability of the polarization show that polarization state ofthe investigated laser fluctuates considerably versus time.
