Barium chalcogenides for nonlinear optics in the mid-IR: Properties and applications
Abstract
The essential properties of BaGa4S7 (BGS), BaGa4Se7 (BGSe), BaGa2GeS6 (BGGS), BaGa2GeSе6 (BGGSe), and Ba2Ga8GeS16 (B2GGS) are reviewed, together with all nonlinear optical applications of these non-centrosymmetric crystals realized so far.
