Second-Order Nonlinear Optical Response of Ba(NO3)2/Al2O3 Nanocomposite

This work presents second-order nonlinear optical investigations of Ba(NO 3 ) 2 /Al 2 O 3 crystalline nanocomposite. Studied sample was obtained by crystal growth in nanoporous Al 2 O 3 membrane. Nonlinear optical studies were characterized by means of second harmonic generation via Maker fringe method and by SHG surface imaging. Additionally, surface of studied crystalline nanocomposite was characterized by scanning electron microscopy (SEM).
