The second-order nonlinear optical properties of κ-phase gallium oxide
Source abstract
Abstract
In this study, we present the first characterization of the effective second-order nonlinear optical susceptibility χeff(2) and the second-order susceptibility tensor element d31 of κ-phase gallium oxide (κ-Ga2O3) using a second harmonic generation (SHG) technique. At the wavelength of 850 nm, we measured a χeff(2) value of 0.1068 pm/V and a d31 value of 0.0566 pm/V. In addition, we investigated the wavelength and polarization dependence of χeff(2). These findings could be a constructive step toward expanding the potential applications of Ga2O3 as a novel optical material platform, complementing its emerging role as a competitive next-generation material for electronics.
