The rotation angle of the polarization of plane of a propagating beam was experimentally measured using a polarization-controlled laser beam, a repeating square mirror, and a discharge apparatus. A rotation angle of 0.29 degrees was obtained for a discharge gap of 5 cm and a charge voltage of 50 kV. This result was in good agreement with a simulation of the experimental model. The waveform of the rotation angle showed a similar time dependence to the discharge current, with a correlation coefficient of >0.94.
