Abstract
The evolution of the second-harmonic signal is monitored as the poled sample is etched with hydrofluoric acid. The sample thickness is measured in real time using an interferometric method. The full set of data allows us to fully reconstruct the nonlinear spatial distribution created inside the glass, whatever the nonlinearities’ origin.Keywords
