Resumen en inglés

Second harmonic generation (SHG) has been obtained in a rich in sodium niobium borophosphate glass by a thermal poling treatment. The thermally poled glass SHG signal has been studied through an original analysis of both transmitted and reflected polarized Maker-fringe patterns. Therefore, the second order nonlinear optical (NLO) efficiency was estimated from the simulation of the Maker-fringe patterns with a stepwise decreasing profile from the anode surface. A reproducible χ(2) susceptibility value as high as 5.0 ±0.3 pm/V was achieved at the anode side. The nonlinear layer, found to be sodium-depleted up to 5 µm deep inside the anode side, identical to the simulated nonlinear zone thickness, indicates a complex space-charge-migration/ nonlinear glass matrix response process.< Leer menos
