Abstract

IR-transparent β - Ge S 2 crystallized glasses were fabricated by crystallization of the glass with a stoichiometric composition corresponding to target crystal and only β - Ge S 2 crystallites were precipitated. A clear second-harmonic generation was observed in the crystallized glasses by the Maker fringe technique. The optical nonlinear susceptibility, χ ( 2 ) , of β - Ge S 2 crystallized glasses was found to be 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.
