ZnTe crystal is widely used for generation and detection of THz radiation. It's suitable for terahertz spectroscopy and terahertz imaging. ZnTe is the most popular choice for THz generation by optical rectification because it can generate extremely short and high-quality THz pulses. ZnTe it the most suitable electrooptic crystal for THz wave emission and detection using a femtosecond Ti:sapphire laser system at 800 nm.
