    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...

    Potassium Titanyle Arsenate (KTiOAsO4), or KTA crystal, is an excellent nonlinear optical crystal for Optical Parametric Oscillation (OPO) application. It has better non-linear optical and electro-optical coefficients, significantly reduced absorption in the 2.0-5.0 µm region, broad angular and temperature bandwidth, low dielectric constants. And its low ionic conductivities  result in higher damage threshold compared with KTP . KTA is often used as an OPO / OPA gain medium for emission in th...

    The Germanium as a mono crystal primarily used in semi-conductor is non-absorptive at 2μm to 20μm IR regions. It is used here as an optical component for IR region applications. Germanium is a high index material that is used to manufacture Attenuated Total Reflection (ATR) prisms for spectroscopy. Its refractive index is such that Germanium makes an effective natural 50% beamsplitter without the need for coatings. Germanium is also used extensively as a substrate for production of optical fi...

    The BaGa2GeSe6 crystal has a high optical damage threshold (110 MW/cm2), a wide spectral transparency range (from 0.5 to 18 μm) and a high nonlinearity (d11 = 66 ± 15 pm/V) , which makes this crystal very attractive for frequency conversion of laser radiation into (or within) the mid-IR range. It was proved probably the most efficient crystal for second harmonic generation ofCO- and CO2-laser radiation. It was found that a broadband two-stage frequency conversion of multi-lineCO-laser radiati...
