Formation of miniature converters on all-optically inserted nonlinear modification

Abstract

Peculiarities of all-optically inserted nonlinear modification in different isotopic materials on a base of glass-matrixes for possible formation of the optical frequency miniature converters are considered. The obtained experimental results of the nonlinear frequency conversion of a visible laser radiation on the all-optically inserted volumetric lattices of the second-order susceptibility, which induce in isotropic samples by action of the pulsed powerful bi-chromatic inter-coherent radiation of YAG:Nd laser, are presented. The investigations of the frequency conversion of the light laser radiation have been performed in potentially perspective materials with variations of the chemical compounds of the fundamental glass-matrixes and also by the small changes of the additional doped concentrates. The separate attention was given to considering the samples with content of the rare-earth elements as perspective ones. The influence of the chemical additions on the properties in process of the nonlinear frequency conversion in different samples is detail analyzed. The miniature converters on all-optically inserted nonlinear modification are perspective in future for micro-optoelectronics and, in particular, for bio-photonics. The work was carried out as a part of Russian State Task FWGW-2025-0012.
