    Chinese wholesale Q Switch - Wollaston Polarizer – Dien

    Wollaston polarizer is designed to separate unpolarized light beam into two orthogonally polarized ordinary and extraordinary components which are symmetrically deflected from axis of initial propagation. This kind of performance is attractive for laboratory experiments as both ordinary and extraordinary beams are accessible. Wollaston polarizers are used in spectrometers also can be used as polarization analyzers or beamsplitters in optical setups. Feature: Separate Unpolarized Light into T...

    Factory Promotional Neodymium Yttrium Aluminum Garnet - Polarizer Rotators – Dien

    Polarization roators offer 45° to 90°rotation at a number of common laser wavelengths.The optical axis in apolarization rotator is perpendicular to the polished face.The result is that the orientation of in put linearly polarized light is rotated as it propagates through the device. Features: Wide Angle Acceptance Better Temperature Bandwidth Wide Wavelength Bandwidth AR Coated,R<0.2%

    Good quality Far Infrared Crystal - Ce: YAG Crystals – Dien

    Ho:YAG Ho3+ ions doped into insulating laser crystals have exhibited 14 inter-manifold laser channels, operating in temporal modes from CW to mode-locked . Ho:YAG is commonly used as an efficient means to generate 2.1-μm laser emission from the 5I7- 5I8 transition, for applications such as laser remote sensing, medical surgery, and pumping Mid-IR OPO’s to achieve 3-5micron emission. Direct diode pumped systems,and Tm: Fiber Laser pumped system have demonstrated hi slope efficiencies, so...

    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...

    Low price for Aggse 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...
