摘要: Evidence that a frozen-in space charge field causes the appearance of high quadratic nonlinearities in thermally poled glass is obtained from experimental tests ratio nonlinear tensor components and spatial distribution induced chi(2). A mechanism to explain fixation chi(2) near anodic surface proposed.
