摘要：

Generation of the second optical harmonic is investigated in 250 to 1500-nm thick films of Ge35Sb5S60 chalcogenide glass. It is shown that a decrease in quadratic optical susceptibility in thicker films can result from a decrease in the bulk contribution from the electric dipole to the susceptibility and can be used in nonlinear optical diagnostics of the films.
