  • Patent number: 4380694
    Abstract: Laser cutting apparatus comprises a laser (20), means (24,25) for directing the output beam of the laser on to a workpiece (26), and means such as a quarter-wave plate (27) for producing circular polarization of the laser output beam. The laser may include within its optical cavity an element which produces stable linear polarization of the output beam. The quarter-wave plate (27) then covers the polarization into circular polarization.
