Imbert–Fedorov Effects of Polarized Laser Beams Reflected from Dove Prism/Indium Tin Oxide Interface under Electric and Thermal Fields

Abstract

Imbert-Fedorov (IF) effects of a polarized laser beam reflected from a dove prism/ indium tin oxide (ITO) interface in the presence of electric and thermal fields are studied using a slit-beam profiler and Stokes polarimeters. The IF effects of the polarized laser beams are primarily influenced by an electric field when the external direct current (DC) voltage is below 1.0 V, and it is mainly influenced by the thermal field when the external DC voltage changes from 1.0 to 4.0 V. The results exhibit a high resolution of 3 Â 10 À3 C, due to the variation of the right-and left-circular polarization properties of the reflected linearly polarized laser beams. In view of this influence of electric and thermal fields on IF effects, the results can be applied in polarization optics, temperature sensing, and light manipulation.
