“…The non-linear optics of intra-band transitions including the third-harmonic generation [95,96] is associated with resonant intra-valence band transitions, second harmonic generation [97,98] and two-photon absorption [99,100]. Polaron dynamics [101,102] has been studied with the absorption saturation technique [103] and pump-probe spectroscopy [104][105][106][107]. Spin mixing effects and spin-lattice coupling have been studied [108] using a THz probe to improve the fundamental understanding of magneto-transport mechanisms in metals [109].…”

Free-Electron Lasers are a rapidly growing field for advanced science and applications, and worldwide facilities for intense field generation, characterization and usage are becoming increasingly popular due to their peculiarities, including extremely bright, coherent, wide band tunable ultra-short pulses which are not achievable with other techniques up to now. In this review we give a thorough survey of the latest advances in the Free-Electron Laser-based field generation and detection methodologies and then present the main characteristics of a future THz/IR source, named TerRa@BriXSinO, based on a superconducting linear accelerator. The foreseen source is strongly monochromatic, with a bandwidth of 1% or smaller, highly coherent both transversally and longitudinally, with extreme versatility and high frequency tunability. After introducing the most recent and novel FEL-assisted scientific investigations, including fundamental explorations into complex systems and time-dependent interactions and material dynamics, we present our vision on the potential use of the TerRa facility and analyze some possible applications, ranging from non-linear physics under extreme conditions to polarization sensitive imaging and metamaterial-based sensing.

“…Tunable, narrow band FEL sources allow the investigation of the sub-molecular aspects of biochemistry with superior analytical performance to investigate hard tissues even down to a single cell. In fact, most bio-processes are in the range of FEL pulse lengths, and time-resolved data on vibrational modes can be obtained [105,201].…”
