KNbO3 Crystal Terahertz Wave Crystal Rainbow Photonics Product Description:

Rainbow Photonics-KNbO3 crystal - Terahertz wave crystal is a widely used optical material. Its excellent optical and optoelectronic properties can be used for component fabrication and optical path construction in electro-optic optics and nonlinear optics. Rainbow Photonics produces crystals with high purity, low scattering loss, high photosensitivity, up to a wavelength of 1000nm, and can interact with Rh, Fe, Mn, and Ni doping for visible and infrared light induced refractive applications. This crystal is not easily deliquescent and has stable chemical properties, making it suitable for manufacturing industrial and scientific optical devices. KNbO₃Crystals have the advantages of high nonlinear efficiency, high electro-optic coefficient, excellent photorefractive performance, high photosensitivity, and low heat dissipation loss, making them very suitable for research in terahertz sources, nonlinear optics, photorefractive, frequency doubling crystals, and other fields.

Rainbow Photonics from Switzerland is a world-class manufacturer of terahertz imaging and spectroscopy products, affiliated with the Nonlinear Optics Laboratory at the Swiss Federal Institute of Technology Zurich, established in 1997. Rainbow Photonics has developed a series of novel THz spectrometer products based on nonlinear organic crystals for THz generation and detection, as well as THz generators and detectors based on efficient organic electro-optic crystals (OH1, DAST, DSTMS), high-quality KNbO3 crystals, and all solid state near-infrared femtosecond lasers. These terahertz systems can be used in industries such as biomedical imaging, security inspections, non-destructive testing, and explosive detection.
