“…In the recent decades, numerous studies have shown that the significant enhancement of optical nonlinearities, − as a consequence of collective oscillation of electron gas in metal that couples with electromagnetic fields, makes noble metallic nanocomposites promising as optical data recording disks, optical waveguides, and all-optical switches. − Different from other noble metallic NPs, silver NPs own lower intrinsic loss of plasmonic energy at visible frequencies that gives rise to SPR. Moreover, the SPR energy of silver NPs is far from the interband transition energy so that analyzing the origin of the optical nonlinearities becomes easier. , In-depth researches indicate that the shape of the metallic NPs and their dielectric environment determine the surface frequency and the nonlinear optical (NLO) properties consequently. − Thus, the size, the volume fraction of metal NPs, and the substrate play an essential role in SPR processing.…”

We report on the enhancement and modulation of nonlinear optical response in an Nd:Y 3 Al 5 O 12 (Nd:YAG) laser crystal through embedded silver nanoparticles (NPs) fabricated by Ag + ion implantation. The linear absorption spectrum of the sample clearly reveals a localized surface plasmon resonance (SPR) band from 350 to 700 nm correlated to the Ag NPs. By using the Z-scan technique with femtosecond pulses at a wavelength of 515 nm, which is considered as an optical excitation within the SPR band, the nonlinear refraction index reaches values as high as ∼10 –12 cm 2 /W, enhanced by ∼4 orders of magnitude in comparison to that of unimplanted Nd:YAG (without Ag NPs). In addition, it has been shown that embedded Ag NPs in the Nd:YAG host reveal saturable absorption signifying the nonlinear responses. We have also observed that the nonlinear absorption coefficients depend significantly on the excitation energy and can be modulated by varying the fluence of Ag + ions.

“…10 (a) 11 B NMR spectrum of sodium borosilicate stiff gel heattreated in different temperatures; (b) 29 Si NMR spectrum of sodium borosilicate stiff gel heattreated in 600 C nanoclusters dispersed in a transparent matrix, such as glass, can exhibit unique and excellent properties compared to the bulk metal material, more and more researchers are focusing on the facile synthesis of metal or metal oxide nanoparticles hybrid materials. Nanometallic glass composites have attracted researchers' great attention, not only because they can be applied to photochromic materials, colored glass circulation industry, and three-dimensional color crafts but also because of their great potential applications in optical materials (Korgel 2013;Chen et al 2001;Zeng et al 2004;Mangin et al 2014;Llordés et al 2013). In all these applications, the particle size, shape, number density, and distribution of nanoparticles together determine the characteristics and performance of the nanometer composite materials.…”

“…This photoreduction process has been achieved by using CW lasers oscillating in the UV [ 18 ] but more often by femtosecond lasers [ 15 – 17 22 ]. Nanosecond laser irradiation has rarely been reported as a source of metal reduction in glasses [ 23 ]. The studies cited indicated that the performance, i.e., the optimal process conditions, depends strongly on the glass type and composition.…”

We present results on laser-assisted formation of two- and three-dimensional structures comprised of gold nanoparticles in glass. The sample material was gold-ion-doped borosilicate glass prepared by conventional melt quenching. The nanoparticle growth technique consisted of two steps – laser-induced defect formation and annealing. The first step was realized by irradiating the glass by nanosecond and femtosecond laser pulses over a wide range of fluences and number of applied pulses. The irradiation by nanosecond laser pulses (emitted by a Nd:YAG laser system) induced defect formation, expressed by brown coloration of the glass sample, only at a wavelength of 266 nm. At 355, 532 and 1064 nm, no coloration of the sample was observed. The femtosecond laser irradiation at 800 nm also induced defects, again observed as brown coloration. The absorbance spectra indicated that this coloration was related to the formation of oxygen deficiency defects. After annealing, the color of the irradiated areas changed to pink, with a corresponding well-defined peak in the absorbance spectrum. We relate this effect to the formation of gold nanoparticles with optical properties defined by plasmon excitation. Their presence was confirmed by high-resolution TEM analysis. No nanoparticle formation was observed in the samples irradiated by nanosecond pulses at 355, 532 and 1064 nm. The optical properties of the irradiated areas were found to depend on the laser processing parameters; these properties were studied based on Mie theory, which was also used to correlate the experimental optical spectra and the characteristics of the nanoparticles formed. We also discuss the influence of the processing conditions on the characteristics of the particles formed and the mechanism of their formation and demonstrate the fabrication of structures composed of nanoparticles inside the glass sample. This technique can be used for the preparation of 3D nanoparticle systems embedded in transparent materials with potential applications in the design of new optical components, such as metamaterials and in plasmonics.
