    Renewable Design for Kd P Eo Q-Switch - Si Windows – Dien

    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...

    OEM/ODM Factory 2100nm Yag - BaGa4Se7 Crystals – Dien

    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...

    2021 Good Quality Laser Alexandrite Yag - Achromatic Waveplates – Dien

    Achromatic waveplates by using two pieces of plates.It is similar to Zero-order waveplate except that the two plates are made from different materials,such as crystal quartz and magnesium fluoride. Since the dispersion of the birefringence can be different for the two materials,it is possible to specify the retardation values at a wavelength range. Features: Spectrally Flat Retardance Operating Ranges from UV to Beyond Telecom Wavelengths AR Coatings for: 260 – 410 nm, 400 – 800 nm, 690...

    Quality Inspection for Silica Window - Tm:YAP Crystals – Dien

    Tm doped crystals embrace several attractive features that nominate them as the material of choice for solid-state laser sources with emission wavelength tunable around 2um. It was demonstrated that Tm:YAG laser can be tuned from 1.91 up to 2.15um. Similarly,Tm:YAP laser can tuning range from 1.85 to 2.03 um.The quasi-three level system of Tm:doped crystals requires appropriate pumping geometry and good heat extraction from the active media.On the other hand,Tm doped materials benefit from a ...
