Sodium niobium borophosphate glass, with a composition of 0.58(0.95NaPO<sub>3</sub>+0.05Na<sub>2</sub>B<sub>4</sub>O<sub>7</sub>)+0.42Nb<sub>2</sub>O<sub>5</sub>, has been<sup> </sup>doped with monovalent silver ions. Second harmonic generation (SHG) has<sup> </sup>been obtained from the poling treatment of this sample. The<sup> </sup>second order nonlinearity from the anode side was estimated from<sup> </sup>an analysis of transmitted polarized Maker-fringe patterns. Thanks to the<sup> </sup>original Maker fringe simulations, a value of 3 pm/V is<sup> </sup>obtained with the silver doped glass that unambiguously scales an<sup> </sup>enhancement of ~35% with respect to the nondoped glass susceptibility.<sup> </sup>For both glasses, the nonlinear layer is found to be<sup> </sup>sodium-depleted up to 4 <i>µ</i>m inside the anode, in accordance with<sup> </sup>quantitative energy dispersive x-ray spectroscopy characterizations. This comparative study indicates<sup> </sup>complex space-charge-migration processes during the poling treatment. The relative enhancement<sup> </sup>of the SHG signal of the silver doped glass is<sup> </sup>correlated with the increase in its linear susceptibility.< Réduire
