Impact of carbon-ion implantation on the nonlinear optical susceptibility of LiNbO_3 Open
In this work we study the impact of ion implantation on the nonlinear optical properties in MgO:LiNbO3 via confocal second-harmonic microscopy. In detail, we spatially characterize the nonlinear susceptibility in carbon-ion impl…
