    Bottom price Bggse Crystal - Dual Wavelength Waveplates – Dien

    Dual wavelength waveplate is widely used on Third Harmonic Generation (THG) system. When you need a NLO crystal for type II SHG (o+e→e), and a NLO crystal for type II THG (o+e→e), the  out put polarization from SHG can not be used for THG. So you must turn the polarization to get two perpendicular polarization for type II THG. Dual wavelength waveplate works like a polarizing rotator, it can rotate the polarization of one beam and remain another beam’s polarization. Recommend Standard W...

    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...

    The YAG (yttrium aluminium garnet) laser can be doped with chromium and neodymium in order to enhance the absorption characteristics of the laser. The NdCrYAG laser is a solid state laser. Chromium ion (Cr3+) has a broad absorption band; it absorbs the energy and transfers it to the neodymium ions (Nd3+) by way of dipole-dipole interactions. Wavelength of 1.064 µm is emitted by this laser. The laser action of Nd-YAG laser was first demonstrated at the Bell Laboratories in the year 1964. The N...

    The AgGaGeS4  crystal is one of the solid solution crystal with extremely tremendous potential among the increasingly developed new nonlinear crystals. It inherits a high nonlinear optical coefficient(d31=15pm/V), a wide transmission range(0.5-11.5um) and low absorption coefficient(0.05cm-1 at 1064nm). Such excellent properties are of enormous benefit to frequency-shifting near-infrared 1.064um Nd:YAG laser into the Mid-infreard wavwlengths of 4-11um. Besides, it has a better performance than...

    Gallium Selenide (GaSe) non-linear optical single crystal, combining a large non-linear coefficient, a high damage threshold and a wide transparency range. It is a is very suitable material for SHG in the mid-IR. The frequency-doubling properties of GaSe were studied in the wavelength range between 6.0 µm and 12.0 µm. GaSe has been successfully used for efficient SHG of CO2 laser (up to 9% conversion); for SHG of pulsed CO, CO2 and chemical DF-laser (l = 2.36 µm) radiation; upconversion of CO...
