Terahertz Organic Crystal Generator Terahertz Organic Crystal Detector

Terahertz Organic Crystal Generator Terahertz Organic Crystal Detector Product Description:

Rainbow Photonics is based on DAST, DSTM, OH1 terahertz organic crystal generator terahertz organic crystal detector, which has high nonlinear sensitivity and high electro-optic coefficient. This THz detector can efficiently generate THz using femtosecond pump pulse optical rectification technology and nonlinear optical difference frequency generation technology, with a working wavelength range of 1.2-1.6 μ m/0.7-0.8 μ m. It has the advantages of high terahertz conversion efficiency, high sensitivity, and high photon conversion efficiency. It is an efficient electro-optical THz detector, which is very suitable for applications such as terahertz generation devices, terahertz detection devices, terahertz time-domain spectroscopy systems, and electro-optical modulation. This detector has multiple aperture sizes to choose from, and products of corresponding specifications can also be customized according to customer needs. In addition, this series of THz terahertz crystals (DAST, DSTM, OH1) have the following characteristics: high photoelectric efficiency, fast response speed, optical rectification, nonlinear difference frequency, 1200-1600nm spectral optimization, and are widely used in terahertz generators, terahertz detectors, optoelectronic modulators, and optical parametric generators.

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.
