— Second harmonic generation (SHG) in ZnS‐based materials is reported. ZnS, ZnS:Cu, Br, and ZnS:Cu, Al, Br samples were studied. Phosphor powders were subjected to 30‐mJ pulses from YAG:Nd infrared laser. The wavelength of the generated green emission was 532 nm, exactly one‐half that of incident laser light (1064 nm). However, the non‐linear dependence of the emission intensity on pump intensity was observed only for the ZnS:Cu, Al, Br powder. It is concluded that aluminum co‐doping is crucial for the non‐linear properties.
