Green Generation and investigation of Optical Properties of Amorphous BaTiO3 by Poling

Abstract

BaTiO3 thin films was deposited on the slide glass by RF sputter We have investigated the optical properties of BaTiO3 film after corona poling process The transmission characteristics was very good over 80% in visible region and second order nonlinear optical coefficient depends on the poling conditions The nonlinear optical coefficient of poled BaTiO3 films was about 1 15pm/V The relaxation of second order nonlinear optical was remained around 60% of the initial value for a long time In addition we have observed the green light generation from BaTiO3 films
