Third‐order optical nonlinear susceptibilities (χ (3) ) of some high‐refractive‐index chalcogenide glasses were evaluated from third‐harmonic generation. Compared with oxide glasses whose χ (3) has been known, χ (3) of the present glasses was higher by an order of magnitude. The addition of selenium drastically increased χ (3) . The highest χ (3) was 1.4 × 10 –11 esu, being comparable with those of high‐χ (3) ‐organic compounds. Further, χ (3) generally increased with increasing density in the present glasses.
