Goos–Hänchen and Imbert–Fedorov shifts of a laser beam reflected from ITO under complex fields

Abstract

Goos–Hänchen (GH) and Imbert–Fedorov (IF) shifts are investigated for P-polarized and S-polarized laser beams reflected from an ITO surface under complex fields. The lateral shifts and polarization properties of the laser beams are obtained by a Slit Beam Profiler and a polarimeter. The GH shifts of the P-polarized laser beam move from 0μm to −180μm, while the IF shifts of the P-polarized laser beam move from 0μm to 180μm when the external direct current voltage increases from 0 V to 2.0 V and when the magnetic field increases from 0 to 60 Oe. Meanwhile, the GH and IF shifts of the S-polarized laser beam are basically unchanged under changing electric and magnetic fields due to the lower Stokes parameter S3.
