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

Abstract Goos-Hanchen (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 0 μ m to − 180 μ m , while the IF shifts of the P-polarized laser beam move from 0 μ m to 180 μ m 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 S 3 .
