Professional China Zgp - BaGa2GeSe6 Crystals – Dien

The BaGa2GeSe6 crystal has a high optical damage threshold (110 MW/cm2), a wide spectral transparency range (from 0.5 to 18 μm) and a high nonlinearity (d11 = 66 ± 15 pm/V) , which makes this crystal very attractive for frequency conversion of laser radiation into (or within) the mid-IR range. It was proved probably the most efficient crystal for second harmonic generation ofCO- and CO2-laser radiation. It was found that a broadband two-stage frequency conversion of multi-lineCO-laser radiati...
Well-designed Ho:Y3al5o12 - 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...
Special Design for Windows For Infrared Band - 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 source Laser Yag Q Switch - Nd:YVO4 Crystals – Dien

Nd:YVO4 is the most efficient laser host crystal for diode pumping among the current commercial laser crystals, especially, for low to middle power density. This is mainly for its absorption and emission features surpassing Nd:YAG. Pumped by laser diodes, Nd:YVO4 crystal has been incorporated with high NLO coefficient crystals ( LBO, BBO, or KTP) to frequency-shift the output from the near infrared to green, blue, or even UV. This incorporation to construct all solid state lasers is an ideal ...
Professional China Zgp - Tm:YAP Crystals – Dien

Tm doped crystals embrace several attractive features that nominate them as the material of choice for solid-state laser sources with emission wavelength tunable around 2um. It was demonstrated that Tm:YAG laser can be tuned from 1.91 up to 2.15um. Similarly,Tm:YAP laser can tuning range from 1.85 to 2.03 um.The quasi-three level system of Tm:doped crystals requires appropriate pumping geometry and good heat extraction from the active media.On the other hand,Tm doped materials benefit from a ...
Wholesale Price Cerium Doped 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...
