| Research Abstract |
Precise polarization rotation measurement like a laser-axion search experiment PVLAS in Italy has been performed and tried the PVLAS inspection. By introducing small dipole magnetic circuit and polarization modulator PEM, high frequency modulation of polarization was achieved, no polarization rotation signal due to magnetic modulation was confirmed. Moreover, we verified our experiment by using Cotton-Mouton effect of nitrogen gas.
