Hot sale Nd Ce Co-Doped Yag - Cr2+: ZnSe – Dien

Cr²+:ZnSe saturable absorbers (SA) are ideal materials for passive Q-switches of eye-safe fiber and solid-state lasers operating in the spectral range of 1.5-2.1 μm. Cr²+:ZnSe can be used in numerous applications, such as free-space communication systems, target designation, time-of-flight range finding, surgery, reflectrometry, laser lidars, etc. DIEN TECH offers Cr²+:ZnSe polycrystals which is appropriate for Q-switching of the lasers operating in the 1.5-2.1 μm spectral range.
New Fashion Design for Ho,Cr,Tm:Yag - ZnS 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...
factory customized Zinc Selenide Lens - Plano-Concave Lenses – Dien

Plano-concave lens is the most common item used for light projection and beam expansion. Coated with antireflective coatings, lenses are used in various optical systems, lasers and assemblies.
Factory making Germanium Lenses - GGG Crystals – Dien

Gallium Gadolinium Garnet (Gd3Ga5O12 or GGG) single crystal is material with good optical, mechanical and thermal properties which make it promising for use in fabrication of various optical components as well as substrate material for magneto-optical films and high–temperature superconductors.It is the best substrate material for infrared optical isolator (1.3 and 1.5um), which is a very important device in optical communication. It is made of YIG or BIG film on the GGG substrate plus birefr...

Chinese wholesale Q Switch - 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...
