    ZnS is a very important optical crystals applied in IR waveband. Transmitting range of CVD ZnS is 8um-14um, high transmittance, low absorption, ZnS with multi-spectrum level by heating etc. static pressure technics has improved the transmittance of IR and visible range. Zinc Sulphide is produced by synthesis from Zinc vapour and H2S gas, forming as sheets on Graphite susceptors. Zinc Sulphide is microcrystalline in structure, the grain size being controlled to produce maximum strength. Multis...

    High-quality crystals of BGSe (BaGa4Se7) is the selenide analogue of the chalcogenide compound BaGa4S7, whose acentric orthorhombic structure was identified in 1983 and the IR NLO effect was reported in 2009, is a newly developed IR NLO crystal. It was obtained via the Bridgman–Stockbarger technique. This crystal exhibits high transmittance over the wide range of 0.47–18 μm, except for an absorption peak at around 15 μm. The FWHM of the (002) peak rocking curve is about 0.008° and the transmi...

    AgGaSe2 crystals have band edges at 0.73 and 18 µm. Its useful transmission range (0.9–16 µm) and wide phase matching capability provide excellent potential for OPO applications when pumped by a variety of different lasers. Tuning within 2.5–12 µm has been obtained when pumping by Ho:YLF laser at 2.05 µm; as well as non-critical phase matching (NCPM) operation within 1.9–5.5 µm  when pumping at 1.4–1.55 µm. AgGaSe2 (AgGaSe2) has been demonstrated to be an efficient frequency doubling crystal ...
