CALCULATION OF THE OPTICAL SECOND HARMONIC GENERATION EFFICIENCY IN THE LITHIUM NIOBATE DOMAIN STRUCTURES

Abstract

The paper presents the experimental and theoretical study results of nonlinear optical properties of lithium niobate domain structures created by a focused electron beam. The presence of a second optical harmonic periodic signal in the locations of the domain structures is shown. The numerical simulation of the second harmonic optical power was done based on the model of Boyd. The possibility of determining the volumetric parameters of domain structures using nonlinear confocal optical microscopy is shown.
