“…Temporal synchronization of the third filament with the as-formed plasma gratings was determined by monitoring the enhancement of the plasma fluorescence induced by the third filament to reach its maximum. By adjusting the three-dimensional position of the fluid jet, we could realize that part of the plasma gratings was formed in air before they entered the fluid jet, 41 as schematically shown in Fig. 1(c).…”

“…39,40 The main difficulty comes from multifilamentation in aqueous solutions as well as relatively low clamped peak intensities closely related to the large optical nonlinearities of aqueous media. 41 In most cases, single filaments in air randomly break up into multifilaments as they enter aqueous solutions. This weakens plasma excitation.…”

Filament-and plasma-grating-induced breakdown spectroscopy (F-GIBS) was demonstrated as an efficient technique for sensitive detection of metals in water, where plasma gratings were established through synchronized nonlinear interaction of two noncollinear filaments and an additional filament was generated with another fs laser beam propagating along their bisector. A water jet was constructed vertically to the three coplanar filaments, overcoming side effects from violent plasma explosion and bubble generation. Three distinct regimes of different mechanisms were validated for nonlinear couplings of the third filament with plasma gratings. As the third filament was temporally overlapped with the two noncollinear filaments in the interaction zone, all the three filaments participated in synchronous nonlinear interaction and plasma grating structures were altered by the addition of the third filament. As the third filament was positively or negatively delayed, the as-formed plasma gratings were elongated by the delayed third filament, or plasma gratings were formed in the presence of plasma expansion of the ahead third filament, respectively. Using F-GIBS for trace metal detection in water, significant spectral line enhancements were observed.

“…[22a, 172] provided spectroscopic evaluation of the attenuation by the SPR of the nanoparticles at the spectral shoulder near the SPR region, which typically coincides to the anti-Stokes wing of supercontinuum in water (Figure 23e-g). The nonlinear scattering properties of plasmonic nanoparticles were further exploited to achieve imaging of gratings formed in nanoparticle-doped water when interacting filaments cross each other [171,173] (Figure 23h).…”

Plasmonic nanocomposites have been extensively studied for over 3 decades. According to early theoretical studies, a large enhancement of nonlinear response has been predicted. Nonetheless, the promised enhancement of coherent or Kerr-type nonlinearities incurs major limitations related to strong absorption and saturation effects. Accordingly, diffraction-limited interactions and long-scale propagation in ultrafast timescales are undermined despite nanoscale-localized electronic field enhancement. Seemingly only nanometric devices operating at low intensity regimes are benefitted from the foresaid effect. Nonetheless, numerous studies have still exploited configurable properties of the nonlinear response of plasmonic nanocomposites, such as nonlinear absorption, high-order nonlinearities, and diffusive nonlinearities for the development of novel processes within the framework of nonlinear wave propagation described by effective medium properties. In this review, the most recent developments on the understanding of the nonlinear response of metals and plasmonic nanocomposites in various temporal regimes are presented. Furthermore, a synthesis of their experimentally determined third-order properties obtained by various experimental techniques, along with practical considerations, is provided. Computational models used for the formulation of nonlinear wave propagation in plasmonic nanocomposites are subsequently presented, corresponding to applicable concepts. Most recent related applications are concisely summarized, indicating the directions of increasing interest in the field, and outlining shortcomings.

“…The simplest PPCs consist of one-dimensional (1D) striated plasma-vacuum or plasma-dielectric layers [2,7]. The most commonly-studied 1D PPCs are laser-produced plasma Bragg gratings [8,9]. Two-dimensional (2D) and three-dimensional (3D) PPCs are arrays of stand-alone plasma structures [4,5] or dielectric/metallic PCs that incorporate repeating plasma structures.…”

A 3D woodpile structure tunable plasma photonic crystal is designed, simulated, and experimentally characterized over the S -X band of the electromagnetic spectrum. The measurements confirm that the electromagnetic response is rich in dynamics. The photonic crystal's reconfigurability, achieved through individual discharge control of the properties of the woodpile plasma columns, offers an unprecedented opportunity to better resolve the interactions between both the Bragg and localized surface plasmon modes which dominate the spectrum at lower frequencies.Both the experiments and simulations reveal evidence for the coupling of Bragg and surface plasmon modes through a Fano resonance. arXiv:1810.02000v1 [physics.app-ph] 3 Oct 2018 3D woodpile structure tunable plasma photonic crystal
