TeraLab (Terahertz spectroscopy laboratory)

Summary:

The TeraLab is the most complete laboratory of its kind in the country. It houses 4 terahertz time-domain spectrometers with different capabilities. We are able to measure complex dielectric function spectra from 20GHz to 3.5THz with a resolution of ~5GHz. We can also produce THz-time-domain images (up to 1m^2) and axial tomography. In addition we are capable of performing optical-pump terahertz-probe experiments with 50fs optical pulses centered between 395nm and 2600nm. We also host the spectroscopy and spectroscopic imaging unit of the National Laboratory of Terahertz Science and Technology. The laboratory is run by the Applied Terahertz Science Group. Our topics of interest are carrier dynamics in solid state materials, non-linear properties of materials, development of novel terahertz optical and photonics devices, as well as applications of terahertz radiation in medicine, biology, biochemistry, industry and cultural heritage investigation and conservation.
