Description

China ZnGeP2 IR Nonlinear Optical Crystal with High-Quality, Leading ZnGeP2 IR Nonlinear Optical Crystal Manufacturers & Suppliers, find ZnGeP2 IR Nonlinear Optical Crystal Factory & Exporters.

Due to possessing large nonlinear coefficients (d36=75pm/V), wide infrared transparency range(0.75-12μm), high thermal conductivity(0.35W/(cm·K)), high laser damage threshold (2-5J/cm2)and well machining property, ZnGeP2 crystal was called the king of infrared nonlinear optical crystals and is still the best frequency conversion material for high power, tunable infrared laser generation. Due to these unique properties, it is known as one of the most promising materials for nonlinear optical applications. ZnGeP2 can generate 3–5 μm continuous tunable laser out put through the optical parametric oscillation (OPO) technology. Lasers, operating in the atmospheric transmission window of 3–5 μm are of great importance for many applications, such as infrared counter measure, chemical monitoring, medical apparatus, and remote sensing. Coupletech can offer high optical quality ZnGeP2 crystals with extremely low absorption coefficient α < 0.05 cm-1(at pump wavelengths 2.0-2.1 µm), which can be used to generate mid-infrared tunable laser with high efficiency through OPO or OPA processes. Cupletech's Capacity: Dynamic Temperature Field Technology was created and applied to synthesize ZnGeP2 polycrystalline. Through this technology, more than 500g high purity ZnGeP2 polycrystalline with huge grains has been synthesized in one run. Horizontal Gradient Freeze method combined with Directional Necking Technology (which can lower the dislocation density efficiently) has been successfully applied to the growth of high quality ZnGeP2 crystals. The kilogram-level high-quality ZnGeP2 crystal with the world's largest diameter (Φ55 mm) has been successfully grown by Vertical Gradient Freeze method. The surface roughness and flatness of the crystal devices, less than 5Å and 1/8λ respectively, have been obtained by our trap fine surface treatment technology. The final angle deviation of the crystal devices is less than 0.1 degree due to the application of precise orientation and precise cutting techniques. ZnGeP2 devices with excellent performance have been achieved because of the high quality of the crystals and high-level crystal processing technology (The 3-5μm mid-infrared tunable laser has been generated with the conversion efficiency greater than 56% when pumped by a 2μm light source). Coupletech's research group, through continuous exploration and technical innovation, has successfully mastered the synthesis technology of high-purity ZnGeP2 polycrystalline, the growth technology of large size and high quality ZnGeP2 single crystal, and crystal orientation and high-precision processing technology; can provide ZnGeP2 devices and original as-grown crystals in mass scale with high uniformity, low absorption coefficient, good stability, and high conversion efficiency. Applications of ZnGeP2 IR nonlinear optical crystals: Second, third, and fourth harmonic generation of CO2-laser; Optical parametric generation with pumping at a wavelength of 2.0 µm; Second harmonic generation of CO-laser; Producing coherent radiation in submillimeterrange from 70.0 µm to 1000 µm; Generation of combined frequencies of CO2- and CO-lasers radiation and other lasers are working in the crystal transparency region. At the same time, we have established a whole set of crystal performance testing platform which makes us have the ability to provide crystal performance testing services for customers. http://www.coupletech.com
