“…For instance, silver nanowire arrays can be successfully employed in surface-enhanced Raman scattering (SERS) [7], nonlinear optics [8], nanobiotechnology [9] and plasmonics [10]. Moreover, silver nanowire arrays embedded in porous alumina templates can serve as wire-grid polarizers which have strong absorption of visible light at a particular frequency [11].…”

“…Our studies reveal that the silver nanoparticles demonstrate comparable or superior nonlinearities to that of nanoparticles synthesised by chemical routes. 28 A 20 gm of home-grown fresh leaves were washed thoroughly with double distilled water (DDW) and added to 100 ml of boiled sterile DDW for 5 minutes and filtered. The extract was stored at 4 C for further experiments.…”

We present a simple and eco-friendly biosynthesis of silver nanoparticles using Coriandrum sativum leaf extract as reducing agent. The aqueous silver ions when exposed to leaf extract were reduced and resulted in silver nanoparticles whose average size is 26 nm. The silver nanoparticles were characterized by UV-Visible, X-ray diffraction (XRD), Fourier transform infra-red spectroscopy (FT-IR) and transmission electron microscopy (TEM) techniques. Nonlinear optical properties of silver nanoparticles were studied using Z-scan technique with 6 ns pulse duration at 532 nm. The nonlinear refractive index and third-order susceptibility 3 were measured to be ∼ 6 0 × 10 −13 cm 2 /W and 1 38 × 10 −9 esu, respectively. Silver nanoparticles were found to exhibit strong reverse saturable absorption (RSA). RSA was identified as the main mechanism responsible for optical limiting.

“…Each particular process, related to the material properties, is characterized by a time-scale [1,2]. For example, thermal [3,4], molecular reorientation [5], and electronic transitions [2] processes have typical time-scales of milliseconds, picoseconds, and femtoseconds, respectively.…”

“…In the second case, the entire transmitted beam is detected by the photodetector and is named open-aperture configuration. The ZS technique has been extensively used to investigate nonlinear properties of different materials [3][4][5][12][13][14][15][16][17]. The Sheik-Bahae formalism (SBF) assumes a local interaction between the sample and the radiation field, disregarding thermal (nonlocal) phenomena, which are considered in the thermal-lens model (TLM) proposed in the 1960s [18][19][20].…”

2012Investigation of the optical absorption of a magnetic colloid from the thermal to the electronic time-scale regime: measurement of the free-carrier absorption cross-section JOURNAL OF THE OPTICAL SOCIETY OF AMERICA B: OPTICAL PHYSICS, WASHINGTON, v. 29, n. 3, pp. 280-285, 2012 The free-carrier absorption cross-section σ of a magnetic colloid composed of magnetite nanoparticles dispersed in oil is obtained by using the Z-scan technique in different experimental conditions of the laser beam. We show that it is possible to obtain σ with picosecond pulsed and millisecond chopped beams with pulse frequencies smaller than about 30 Hz. For higher pulse frequencies, the heating of the colloidal system triggers the appearance of the Soret effect. This effect artificially increases the value of σ calculated from the experimental results. The limits of the different experimental setups are discussed.
