SapienzaTerahertz Laboratory
Sapienza Research Infrasturcture
Manager: Prof. Massimo Petrarca
SapienzaTerahertz Laboratory and research group of Prof. Massimo Petrarca is located at the Department of Basic and Applied Sciences for Engineering (SBAI), Sapienza University of Rome (Rome, Italy).
It is equipped with the state-of-the art THz technology for high-precision spectroscopy and imaging.
It hosts high power QCL THz sources, a 2D high-sensitivity microbolometer camera working at room temperature, high-resolution coherent THz spectroscopy systems (THz-CW and THz-TDS) based on photoconductive antennas, and a high-spectral resolution FT-IR gas analyzer.
The facility is open for any collaboration from Scientific research to Industrial applications. For any inquiries please feel free to contact Prof. Massimo Petrarca: massimo.petrarca@uniroma1.it
THz-QCL
Terahertz Quantum Cascade Laser system (EasyQCL-110, LongWave Photonics LLC, Mountain View, CA) covers from 1.6 THz to 4.3 THz from a single device. The image acquisition system can work both in transmission and reflection mode and can be applied for broadband spectroscopy and hyperspectral imaging.
THz microbolometer camera
The terahertz uncooled microbolometric camera (MICROXCAM-384i-THz, INO, Canada) provides unrivalled sensitivity and image quality over a wide spectral range.
THz-CW
Terahertz continuous wave (THz-CW) system (TeraScan 100 1550, TOPTICA Photonics AG, Germany) working in the frequency range 50-2840 GHz.
The system has a high terahertz power and a high-frequency resolution. The compact structure of the lasers units make the spectroscopic system portable for on-field measurements.
Airborne THz spectrometer
The terahertz-on-drone system is engineered combining a high-resolution THz-CW laser technology with an unmanned aerial system (UAS) and can be exploited to detect atmospheric gases that represent environmental pollutants. The setup is engineered to perform point-like remotely controlled measurements and to identify and quantify substances in real-time.
THz-TDS
Terahertz time domain spectroscopic (THz-TDS) system (TeraFlash pro, TOPTICA Photonics AG, Germany) working in the frequency range 0.1-7 THz.
The system achieves a peak dynamic range of 100 dB, and a bandwidth of more than 6 THz. A highly precise mechanical delay stage allows a fast time acquisition.
FT-IR
A high-performance FT-IR gas analyzer (MATRIX II-MG5, Bruker, Germany) working in the range 4800 - 720 cm-1 with a spectral resolution down to 1 cm-1 and an optical path of 5 m.
