SapienzaTerahertz: THz spectroscopic image system for basic and applied sciences

Lingua Italiano

The laboratory is equipped with

a state of the art Quantum Cascade Laser (QCL) THz sources with emission powers in the mW range and between (1.9-5) THz;

a state of the art 2D sensor composed of microbolometers at room temperature (and other pyroelectric sensors).

a high resolution (down to 10 MHz) coherent spectroscopy system at THz frequencies composed by a combination of photoantennas and IR lasers in optical fiber.

A versatile THz source from high-brightness electron beams: Generation and characterization

Ultra-short electron bunches, such as those delivered by a high-brightness photo-injector, are suitable to produce high peak power THz radiation, both broad and narrow band, with sub-picosecond down to femtosecond pulse shaping. The features of this kind of source in the THz range of the electromagnetic spectrum are extremely appealing for frequency-and time-domain experiments in a wide variety of fields.
