Abstract :
In this work we present a practical and nondestructive technique for measuring the thickness and the magnitude of χ(2) in thermally poled glasses. Theoretical analysis shows that thickness, as small as 4 μm, can be measured with less than 10% error. The resolution is estimated in about 1 μm. The technique is tested on a set of poled silica sample and the poling dynamic as well as the χ(2) evolution are derived.
