The new nonlinear optical material Sr3MnSn2S8 is a noncentrosymmetric structure with a large band gap of 3.02 eV. In addition, Sr3MnSn2S8 possesses a good second harmonic generation (SHG) response, approximately equivalent to that of AgGaS2, and a high laser damage threshold (LDT) about 3 times that of AgGaS2 (AGS).

From CuFeS2, the introduction of Ge leads to an increase in band gap. The ordered arrangement of NLO active units [GeS4] results in a strong SHG response. Finally, Ba6Cu2FeGe4S16 exhibits good NLO performance (SHG, 1.5 × AgGaSe2; LDT, 2 × AgGaSe2).

Preliminary Study

ABSTRACTRecent activity in the development of nonlinear optical (NLO) materials with high second order susceptibilities has prompted the development of a wide variety of pendant polymers which possess desirable properties for device development, including high Tg minimal relaxation of the poled matrix, and high laser damage threshold. Ideal candidates for such systems are asymmetrically substituted oligomers of polyacetylenes such as dimethylaminonitrostilbene (DANS) and corresponding higher order oligomers. We report here a preliminary study of the synthesis of asymmetrically substituted donor/acceptor diphenyl-capped polyenes and thienylene vinylene oligomers attached as pendant moieties on polyvinylphenol (PVP) for second harmonic generation.
