“…9,10 With the development of high-power lasers operating in cw or pulsed modes, the region of possible methods of acceleration was significantly expanded. 11 For the laser acceleration of microparticles, except for light pressure, several mechanisms exist: [12][13][14][15] heating and motion of a medium ͑convective motion͒; heating of the surface of an absorbing particle ͑radio-metric motion͒; and pressure at particle evaporation ͑reaction pressure͒. When the absorbing coefficient is high, all these mechanisms can be much more significant than the light pressure.…”

“…When the absorbing coefficient is high, all these mechanisms can be much more significant than the light pressure. Investigation of acceleration of particles by light pressure and some practical applications has been demonstrated, [12][13][14] where the laser-induced particle's motion in dense random media, when laser beam accelerated particles flow inside a cylindrical region, was investigated.…”

Surface-enhanced Raman scattering was applied to study the nanodiamond with particles’ sizes 100 and 5 nm, positioned on silver (Ag) substrate using high focused laser beam acceleration method. The nanodiamond particles suspended in distilled water were accelerated by a near infrared laser beam and attached to an Ag foil serving as the target. This allows the nanodiamond particles to be ordered, positioned, and to penetrate deep into Ag. The nanodiamond–Ag surface structure after nanoparticles∕laser beam treatment was analyzed using micro-Raman spectroscopy and scanning electron microscopy. Strong interaction between the nanodiamond and Ag surface can be achieved, which allows us to observe surface-enhanced Raman scattering (SERS). The most significant enhancement observed for carbon was trans-polyacetylene bands in addition to the D and G bands. The enhancement can achieve orders in magnitude both for 100 and 5 nm nanodiamonds. The selective enhancement of some composite band intensity, a characteristic feature of SERS referred to as the blinking effect, was also observed.

“…Theoretical analysis of the temporal correlation function of multiple-scattered waves has been extended to amplifying disordered media, 23 as well as to the case of intense incident waves producing flows of scatterers in the disordered medium. 24,25 An additional contribution to C δI (r, τ ), originating from scattering in the immediate neighborhood of source and/or detector, decaying much slower than all the previously known contributions, is predicted to exist. 14 High sensitivity of multiple-scattering speckle patterns to scatterer motion gave rise to a new technique for studying the scatterer dynamics in disordered, turbid media, the so-called "diffusing-wave spectroscopy" (DWS).…”

We consider the multiple scattering of a scalar wave in a disordered medium with a weak nonlinearity of Kerr type. The perturbation theory, developed to calculate the temporal autocorrelation function of scattered wave, fails at short correlation times. A self-consistent calculation shows that for nonlinearities exceeding a certain threshold value, the multiple-scattering speckle pattern becomes unstable and exhibits spontaneous fluctuations even in the absence of scatterer motion. The instability is due to a distributed feedback in the system "coherent wave + nonlinear disordered medium". The feedback is provided by the multiple scattering. The development of instability is independent of the sign of nonlinearity.

“…In the opposite case Savchenko et al [10], theoretically showed for the first time that it should be possible to induce a convective flow, by transfer of momentum from light to a liquid crystal. Skipetrov et al [15,16] demonstrated that multiple scattering events also drive bulk flow and measured the scatterer velocity by determining the temporal autocorrelation function of the scattered electromagnetic field. Later Casner and Delville [17] strongly deformed very soft fluid/fluid interfaces in near critical thermodynamic conditions using the optical radiation pressure.…”
