“…Typically one can produce few-cycle strong THz sources, which are particularly interesting for nonlinear and non-equilibrium studies, including THz nonlinear optics, THz pump experiments on coherent control of structure dynamics of various matters, control of chemical reactions, high magnetic field effects, etc. [3,4]. For THz radiation produced by femtosecond laser-gas interaction, a well-known mechanism is the ionization current, which can be effectively produced by two-color lasers or by few cycle lasers [5,6].…”

These THz pulses are shown to emit from both the front and rear sides of the solid target and are attributed to the coherent transition radiation (CTR) by laserproduced ultrashort fast electron bunches. After the primary THz pulses, subsequent secondary half-cycle pulses are generated while some refluxing electrons cross the vacuum-target interfaces. Since such strong THz radiation is well synchronized with the driving lasers, it is particularly suitable for applications in various pump-probe experiments.

“…With these schemes, it is difficult to obtain high-power THz emission at the megawatt level, as is needed for many applications and for the study of high-field and nonlinear physics in the THz regime in semiconductors, insulators, superconductors, etc. [37]. Currently, MW narrow-band THz sources are obtained from free-electron lasers.…”

This review covers recent developments in multi-hundred-TW femtosecond laser systems and progress in intense laser-plasma interactions at the Institute of Physics, Chinese Academy of Sciences. The peak power of the institute's Xtreme Light III (XL-III) laser system has been upgraded from 350 to 725 TW, and the system used to observe the lateral transport of fast electrons due to magnetic and electrostatic fields at target surfaces. The surface fields cause fast-electron beams to be emitted along the front and rear target surfaces. Confinement and guiding of fast-electron propagation is demonstrated with wire-or wedge-shaped targets. Longitudinal transport is detected by optical and ion emission. Numerical simulations show that quasi-monoenergetic ion beams can be generated by collisionless electrostatic shock acceleration and phase-stable acceleration with a circularly polarized laser field. A new mechanism for high-power THz emission with plasmas as media is proposed; it can be used to obtain a single-cycle THz emission. The conversion efficiency from laser energy to K α X-ray emission in a laser-copper target interaction is increased to 10 −4 using high-contrast laser pulses.

“…They are particularly attractive for molecular fingerprint spectroscopy, since rotational excitations in many molecules of interest such as drugs, explosives and poisonous contamination fall within the THz region of the spectrum [1][2][3]. Additionally, THz waves are important for quantum coherence experiments [4], and are instrumental in radio-astronomy [5].…”

The interference between two spectral lines of the frequency comb of a fiber femtosecond laser is used to generate millimeter-wave and terahertz tones. The two lines are selected by stimulated Brillouin scattering (SBS) amplification. All other modes are strongly rejected based on polarization discrimination, using the polarization-pulling effect that is associated with SBS. The inherent high spectral quality of a femtosecond fiber laser comb allows generation of millimeter-and terahertz waves with linewidths below 1 Hz, and a phase noise of -105 dBc/Hz at 10 kHz offset. The generation, free-space transmission and detection of continuous waves at 1 THz are demonstrated as well. Lastly, the generated millimeterwave carriers are modulated by 40 Gbit/s data. The entire system consists of a fiber laser and standard equipment of optical telecommunications. Besides metrology, spectroscopy and astronomy, the method can be utilized for the emergent field of wireless millimeter-wave and THz-communications at ultra-high data rates.
