Large Nonlinear Susceptibility: ZnGeP2 crystals have a large nonlinear susceptibility (d36 ~ 75 pm/V), which is approximately 160 times that of KDP (potassium dihydrogen phosphate). This high nonlinear susceptibility makes ZGP crystals highly efficient for nonlinear optical processes.

Wide Transparency Range: ZGP crystals are optically transparent over the 0.74–12 μm wavelength region. This wide transparency range allows for versatile use in various optical systems and applications.

High Laser Damage Threshold: ZnGeP2 crystals have a relatively high laser damage threshold, making them suitable for high-power laser systems and applications that require intense laser beams.

Tunable Laser Output: ZGP crystals are recommendable for producing tunable laser output in the near-infrared spectrum. This capability makes them valuable for applications that require precise control over laser wavelength.

Applications: Laser Technology, Optical Parametric Oscillator (OPO), Optical Parameter Generation/Amplification (OPG/OPA), Frequency Conversion, Scientific research, Medical & Biological Imaging, etc.
