| 摘 要： | To find materials with larger second-order nonlinearity, the Ge-P-S chalcogenide glasses with various ratios of GeS2 ： P2S5 were prepared by the melt-quenching method. The microstructure and optical properties of these glasses were characterized by XRD, Raman, Vis- NIR speetroscopy and Maker fringe technique. The second harmonic generation （SHG） was observed in the as-prepared chalcogenide glasses which was ascribed to the thermal stress gradient and/ or the rnicroanisotropic defects （ such as the lone-pair orbital or the valence alternative pairs ） prefer-orientation of the as-prepared glasses.
