Abstract The concept of Terahertz Field-Induced Second Harmonic (TFISH) Generation is revisited to introduce a single-shot detection scheme based on third order nonlinearities. Focused specifically on the further development of THz plasma-based sourc

We report the observation of terahertz field-induced second harmonic (TFISH) generation produced by directly mixing an optical probe beam onto femtosecond plasma filaments. The produced TFISH signal is spatially separated from the laser-induced super

We experimentally investigate the dielectric response of two different liquid samples through nonlinear terahertz spectroscopy. Our results indicate that the nonlinear indexes of refraction of these liquids in the terahertz frequency range are up to

Nonlinear THz spectroscopy extends the full-phase analysis of traditional THz-TDS onto the high-intensity regime. With THz sources reaching peak electric fields in excess of hundreds of kV/cm, it is now possible to induce large index changes in some

THz liquid photonics is a new research frontier in laser-matter interaction community. We have successfully demonstrated THz wave generation from ionized liquids, including from liquid water, liquid nitrogen, and liquid gallium. Preferable to general

Nanoparticles are a favorable way to enhance ionization for ultrashort laser pulse focusing on liquid targets. We experimentally investigate how nanoparticles affect the THz generation from deionized water for different concentrations. However, no ob

We characterize a terahertz (THz) source based on plasma in liquid gallium. The dependence of the emitted THz pulse energy on second-order phase, pump pulse energy, and polarization of the short laser pulse is demonstrated. Our study suggests that th

We experimentally show the spectrally averaged nonlinear refractive index and absorption coefficient for liquid water, water vapor, {\alpha}-pinene, and Si using a full-phase analysis in the terahertz regime through a standard time-domain spectromete
