Influence of Mg and/or Be Content on Nonlinear Optical Properties of A2B6 Crystals

摘要

In this paper, we present some nonlinear optical properties of A2B6 mixed crystals grown by the modified high-pressure Bridgman method. We measured the nonlinear refractive index (n2), third order nonlinear optical susceptibility (χ<3>) and nonlinear absorption coefficient of these semiconductors using the standard backward degenerate four wave mixing (DFWM) and Z-scan techniques.
