Nlo Property

AbstractThe molecular structure / nonlinear optical (NLO) property relationship is explored with seven recently synthesized chromophores. Two symmetrical compounds were made using electron withdrawing groups separated by an electron rich core while five asymmetrical molecules were developed using electron donating and withdrawing groups coupled by a it electron bridging group. Pendant chains were added to some of the chromophores to improve processibility. Their syntheses are described and their optical limiting properties discussed.

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.
