Product Description

Infrared ZnGeP2 (ZGP) crystals have transmission band edges at 0.74 and 12 µm. However their useful transmission range is from 1.9 to 8.6 µm and from 9.6 to 10.2 µm. IR Nonlinear Crystal ZnGeP2 have the largest nonlinear optical coefficient and relatively high laser damage threshold. NLO Crystals ZGP crystals can successfully be used in diverse applications: Up-conversion of CO2 and CO laser radiation to near IR range via harmonics generation and mixing processes, efficient SHG of pulsed CO, CO2 and chemical DF-laser, and efficient down conversion of Holmium, Thulium and Erbium laser wavelengths to mid infrared wavelength ranges by OPO process.

Coupletech Co., Ltd. offer IR materials ZGP crystals with high damage threshold BBAR coatings and the lowest absorption coefficient α < 0.05 cm-1 (at pump wavelengths 2.05 - 2.1 µm) for OPO applications. Typical absorption coefficient is <0.03 cm-1 at 2.5 - 8.2 µm range. Due to possessing large nonlinear crystal 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, IR materials 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.

ZnGeP2 crystal IR crystal
Due to these unique properties, it is known as one of the most promising materials for nonlinear optical applications. ZGP 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.
Our Capacity:
Dynamic Temperature Field Technology was created and applied to synthesize ZGP polycrystalline. Through this technology, more than 500g high purity ZGP 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 ZGP crystals.
The kilogram-level high-quality ZGP crystal with the world's largest diameter (Φ55 mm) has been successfully grown by Vertical Gradient Freeze method.
The crystal 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).
We can provide ZnGeP2 devices and original as-grown crystals in mass scale with high uniformity, low absorption coefficient, good stability, and high conversion efficiency. 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.
