High Quality for Madical Laser Crystal - CaF2 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...
China Supplier Saturable Absorbers - Nd,Cr:YAG Crystals – Dien

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...
Factory best selling Nd Yag Laser Rod - Ge Windows – Dien

The Germanium as a mono crystal primarily used in semi-conductor is non-absorptive at 2μm to 20μm IR regions. It is used here as an optical component for IR region applications. Germanium is a high index material that is used to manufacture Attenuated Total Reflection (ATR) prisms for spectroscopy. Its refractive index is such that Germanium makes an effective natural 50% beamsplitter without the need for coatings. Germanium is also used extensively as a substrate for production of optical fi...
High reputation Er Doped Glass - AgGaS2 Crystals – Dien

AGS is transparent from 0.50 to 13.2 µm. Although its nonlinear optical coefficient is the lowest among the mentioned infrared crystals, high short wavelength transparency edging at 550 nm is made use of in OPOs pumped by Nd:YAG laser; in numerous difference frequency mixing experiments with diode, Ti:Sapphire, Nd:YAG and IR dye lasers covering 3–12 µm range; in direct infrared countermeasure systems, and for SHG of CO2 laser. Thin AgGaS2 (AGS) crystal plates are popular for ultrashort pulse ...

Lowest Price for Erbium，Chromium Doped Yttrium Scandium Gallium Garnet - GaSe Crystal – Dien

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...
