Laser Light Durability and Nonlinear Optical Properties of Acrylate Polymer−Chalcogenide Glass−Gold Nanocomposites

Abstract

Synthesis of acrylate‐based nanocomposites (NCs) for photonic applications is performed, and the influence of gold and chalcogenide glass nanoparticles (NPs) on optical parameters of NC layers at high laser intensities is investigated, whereas the polymerization, recording of optical gratings or other elements, and variations of their functional parameters in As2S3 and Au‐containing NC layers are possible at low, 532 nm laser light intensities in the absorption edge range; optical stability under high intensity illumination and threshold laser damage intensities in NIR optical transmission range are important for nonlinear optical experiments, measurements of n2. Hence, these parameters are determined and show the increase in NCs’ stability due to the addition of Au NPs, as well as increase in n2 in gold‐ and chalcogenide‐containing NCs. Thus, the functionality of such NCs and optical elements on their basis can be extended to high‐intensity applications and nonlinear optics.
