Abstract

Nonlinear refractive indexes and two-photon absorption coefficients of new biosilicate nanocomposite materials based on precursor tetrakis (2-hydroxyethyl) orthosilicate (Si-precursor THEOS) were determined by created portative automation measuring complex based on Z-scan technique. Influence of different additives on nonlinear optical properties such media is considered. Energy thresholds of forming filaments and the efficiency of conversion initial radiation in supercontinuum in the range 400-700 nm are considered.
