  • Abstract
    A technique for polarizing a high-power laser with unstable resonator optics that places the polarizing elements in a low power feedback path external to the parent resonator structure is described. The technique has been used to polarize a high-power industrial CO2 laser. Rejection ratios for the unwanted polarizations can exceed 20 dB. The polarization vector can be rotated at will by rotating the polarizer in the low power beam path
