    High Quality Nd Yag 532 - Er:YAP Crystals – Dien

    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...

    Hot-selling Nd Yag - 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 Supply Aggs Crystal - Glan Taylor Polarizer – Dien

    Glan Taylor polarizer is made of two same birefringent material prisms that are assembled with an air space.Its length to aperture ratio which is less than 1.0 makes it a relatively thin polarizer.The polarizer with no side escape windows is suitable for low to medium power application where the side rejected beams are not required .The angular field of different materials of polarizers is listed below for comparison. Feature: Air-spaced Close to Brewster’s Angle Cutting High Polariza...

    Factory Cheap Hot Shg 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...
