摘要
IR-transparent beta-GeS2 crystallized glasses were fabricated by crystallization of the glass with a stoichiometric composition corresponding to target crystal and only beta-GeS2 crystallites were precipitated. A clear second-harmonic generation was observed in the crystallized glasses by the Maker fringe technique. The optical nonlinear susceptibility, chi((2)), of beta-GeS2 crystallized glasses was found to be similar to 7.3 pm/V, being comparable to that created by thermal/electric or other poling methods, which opens a new way to an optical converter operating in the mid-IR spectral region.
