Lasers and laser-related equipment. Test methods for laser beam parameters. Polarization1 Scope This International Standard specifies a method for determining the polarization status and, whenever possible, the degree of polarization of the beam from a continuous wave (cw) laser. It can also be applied to repetitively pulsed lasers, if their electric field vector orientation does not change from pulse to pulse. This International Standard also specifies the method for determining the direction of the plane of oscillation in the case of
