“…In this section some specific examples of applications of thirdorder optical characterization using FWM, including Phase Conjugation and optical Kerr gate (OKG), will be presented. FWM has found applications in practically any media from gases, liquids, and solids [17,28,[33][34][35], including semiconductors [36], nanostructured materials [37], photorefractive crystals [38], molecules and polymers [39], and graphene [40]. Phase Conjugation, which is one of the most frequently applied varieties of FWM, has been exploited in many different fields [17] due to its ability to correct for wavefront distortion, which is very important for biological applications [41].…”

Various techniques to characterize the nonlinear (NL) optical response of centro-symmetric materials are presented and evaluated with emphasis on the relationship between the macroscopic measurable quantities and the microscopic properties of photonic materials. NL refraction and NL absorption of the materials are the phenomena of major interest. The dependence of the NL refraction and NL absorption coefficients on the nature of the materials was studied as well as on the laser excitation characteristics of wavelength, intensity, spatial profile, pulse duration and pulses repetition rate. Selected experimental results are discussed and illustrated. The various techniques currently available were compared and their relative advantages and drawbacks were evaluated. Critical comparisons among established techniques provided elements to evaluate their accuracies and sensitivities with respect to novel methods that present improvements with respect to the conventional techniques.

“…Ultrafast nonlinear electrodynamics of laser-induced plasmas opens a vast landscape of light–matter interaction scenarios, , providing a powerful resource for ultrafast optical science and high-field laser physics. , Standing out as one of the most interesting effects in ultrafast laser–plasma physics is the generation of terahertz (THz) and sub-THz field waveforms by laser-induced filaments (LFs) and laser-driven plasmas (LPs) in gases and solids. − Physical scenarios enabling the generation of such field waveforms have been at the focus of intense research within the past years, aiming at understanding the complex physics behind THz generation − and identifying the laser–plasma interaction regimes whereby the highest THz yields could be produced. − …”

Polarization and Spatial Mode Structure of Mid-Infrared-Driven Terahertz-to-Microwave Radiation

et al. 2021

Polarization-and angle-resolved analysis of microwave-to-terahertz (μWv/THz) radiation from gas-phase plasmas induced by ultrashort mid-infrared laser pulses reveals a complex vectorial electrodynamic picture of μWv/THz generation by a diverse manifold of laser-driven plasma currents and provides a powerful tool to distinguish between currents of different spatial symmetries as sources of μWv/THz radiation. In experiments with a single-color mid-IR driver, the spatial mode of μWv/THz radiation is found to retain a remarkably uniform, conical-emission structure across its entire spectral span, with angular dispersion and a spatial mode profile as dictated by Cherenkov-type phase matching. This spatial mode structure is consistent with its polarization properties of μWv/THz radiation, indicating the dominant role of radiation by ponderomotively driven longitudinal currents. In experiments with a two-color laser driver, the spatialpolarization mode structure of μWv/THz radiation is found to change across its spectrum and as a function of the gas pressure, revealing mixed symmetries of underlying electric currents and indicating the shifting roles of transverse and longitudinal currents as mechanisms behind μWv/THz generation.
