Infrared nonlinear optical (IR-NLO) materials are the key components in solid-state lasers for military and civilian applications. The development of IR-NLO remains urgent because existing commercial AgGaS2 (AGS), AgGaSe2, ZnGeP2 limited their own intrinsic shortcomings, example, lower laser damage thresholds (LDTs), non-phase-matchable feature, strong two-photon absorption, respectively, exhibited AgGaSe2 at a conventional 1 μm. Chalcogenides, halides, iodates known to be common sources potential with good properties, which most in-depth studied is usually constructed by single anions. Recently, mixed-anion inorganic compounds thought promising can optimize comprehensive performances, especially balance incompatibility between large NLO coefficient high LDT one material. This review focuses on syntheses crystal structures materials, as well relationships structure–property. Examples include four kinds such compounds, i.e., chalcogenides, chalcohalides, other miscellaneous including adducts, oxychalcogenides, oxyhalides, iodate fluorides, selenite halide borates. work gives some exploring directions novel how performances from inferred structure–property compounds.
