Top Suppliers Baga2gese6 Crystal - BBO crystal – Dien

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...
Manufacturer of 1064 Q Switch - Ho: 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...

8 Year Exporter Beauty Q Switch - Interference Filters – Dien

DIEN TECH provides high quality standard and custom-made narrow bandpass interference filters within the spectral range from 200 nm to 2300 nm.
Low price for Yag - Achromatic Waveplates – Dien

Achromatic waveplates by using two pieces of plates.It is similar to Zero-order waveplate except that the two plates are made from different materials,such as crystal quartz and magnesium fluoride. Since the dispersion of the birefringence can be different for the two materials,it is possible to specify the retardation values at a wavelength range. Features: Spectrally Flat Retardance Operating Ranges from UV to Beyond Telecom Wavelengths AR Coatings for: 260 – 410 nm, 400 – 800 nm, 690...
Hot-selling Nd Yag - KTA Crystal – Dien

Potassium Titanyle Arsenate (KTiOAsO4), or KTA crystal, is an excellent nonlinear optical crystal for Optical Parametric Oscillation (OPO) application. It has better non-linear optical and electro-optical coefficients, significantly reduced absorption in the 2.0-5.0 µm region, broad angular and temperature bandwidth, low dielectric constants. And its low ionic conductivities result in higher damage threshold compared with KTP . KTA is often used as an OPO / OPA gain medium for emission in th...
