Soda lime glasses polarized either with an open or a blocking anode have been characterized by IR reflectance spectroscopy and a combined analysis of second harmonic generation and Raman imaging. The experimental results clearly show that the electrode nature influences strongly (i) the thickness of the space charge layer, (ii) the X((2)) efficiency, and (iii) the structural rearrangements. Besides, using theoretical models accounting for charge carriers' mobilities, the respective influence of two distinct compensation mechanisms, that is an injection of positive charges (H(3)O(+)/H(+) ions) or a drift of oxygen ions, have been confirmed.
