英文摘要	In this paper we investigate the propagation of an intense linearly polarized laser through an ionizing gaseous medium in the presence of an axial strong magnetic field, addressing the modulation of laser polarization. Our simulation indicates that the laser polarization can be dramatically modulated and shows complicated temporal patterns (Lissajous curves). This striking phenomenon can be attributed to the collective movement of ionized electrons, in contrast to the traditional Faraday rotation in which the rotation angle of the laser polarization derived from the linear response of the medium is time independent. We take the weighted average of the rotation angle over the whole pulse duration and find that it explicitly relies on strong magnetic strength as well as the incident laser intensity. Our finding has implications in strong magnetic diagnosis, laser intensity calibration, and the generation of polarization-modulated light sources.; Optics; Physics, Atomic, Molecular & Chemical; SCI(E); EI; 0; ARTICLE; liu_jie@iapcm.ac.cn; 4; 90
