    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...

    Yttrium aluminium oxide YAlO3 (YAP) is an attractive laser host for erbium ions due to its natural birefringence combined with good thermal and mechanical properties similar to those of YAG. Er:YAP crystals with high doping concentration of Er3+ ions are typically used for lasing at 2,73 microns. Low-doped Er:YAP laser crystals are used for of the eye-safe radiation at 1,66 microns by in-band pumping with semiconductor laser diodes at 1,5 microns. The advantage of such a scheme is low thermal...

    AGS is transparent from 0.50 to 13.2 µm. Although its nonlinear optical coefficient is the lowest among the mentioned infrared crystals, high short wavelength transparency edging at 550 nm is made use of in OPOs pumped by Nd:YAG laser; in numerous difference frequency mixing experiments with diode, Ti:Sapphire, Nd:YAG and IR dye lasers covering 3–12 µm range; in direct infrared countermeasure systems, and for SHG of CO2 laser. Thin AgGaS2 (AGS) crystal plates are popular for ultrashort pulse ...
