Investigations of nonlinear optical characteristics (nonlinear refractive indices, nonlinear absorption coefficients and third-order nonlinear susceptibilities) of copper and silver nanoparticles implanted in glasses are presented using picosecond Nd : YAG laser radiation (λ = 1064 nm) and the Z-scan technique. The variations of the sign of the nonlinear refractive indices depending on matrix properties are analyzed. It is shown that the nonlinear absorption in copper-doped glasses is due to the two-photon effect. The optical limiting properties of these materials are discussed in the framework of two-photon absorption.

“…All these measurements were carried out using UV [8], visible (532 nm [6], 570 nm [7], 420 nm [5]) or 800-nm radiation [4]. At the same time it is interesting to analyze the behavior of such nanoparticledoped glasses in the infrared range using photons with an energy far below the SPRs of these materials.…”

“…[17][18][19] It is now well-understood that the nonlinear properties of metal fi lms and nanoparticles dramatically depend on fi lm roughness and morphology and nanoparticle size distribution and shape. [20][21][22][23][24] What we report here is distinctively different from this body of prior work: we demonstrate a new strategy for achieving an extremely fast engineered optical nonlinearity through nanoscale periodic sub-wavelength patterning of thin metal fi lms. This leads to a resonant, orders of magnitude enhancement of the cubic nonlinear response of the metal.…”

“…The efficiency of the nonlinear optical response of such materials depends on the MN concentration [1]. The nanoparticles-containing composite materials have short response time and high Kerr nonlinear susceptibility and can be used as ultra-fast optical switchers and limiters.As it was shown in earlier studies of copper nanoparticles embedded in insulator matrices, the tendency was to investigate the influence of MN size and preparation methods [2,3] on their nonlinear refractive index [4], third-order nonlinear susceptibilities and time response [5]. At the same time, such materials possess the enhanced nonlinear absorption properties, in particular negative nonlinear absorption (NNA), i.e.…”

PACS 42.65. An, 42.70 Jk, 78.20.Ci Nonlinear absorption in copper-doped silicate glasses was investigated by the Z-scan technique using second harmonic radiation of a Nd : YAG laser (λ = 532 nm, τ = 55 ps). The simultaneous influence of saturated and reverse saturated nonlinear absorption processes was analyzed. The nonlinear absorption coefficient and the saturation intensity of copper-doped glasses at laser intensity of 5.4 × 10 9 W cm -2 were measured to be 6 × 10 -6 cm W -1 and 4.3 × 10 8 W cm 1 Introduction Nonlinear optical properties of the structures containing metal nanoparticles (MN) are of great interest due to their possible applications in optoelectronics and laser physics. Silver, gold, cobalt, platinum, and copper nanoparticles were the mostly investigated MN, as dispersed in various insulator matrices. Several mechanisms contribute to the third-order nonlinearities in small metal nanoparticles, including surface plasmon resonance (SPR) enhancement, intraband transitions in the quantum confined conduction band (quantum size effect), interband transitions between the d band and the conduction band, and nonequilibrium electron heating. The efficiency of the nonlinear optical response of such materials depends on the MN concentration [1]. The nanoparticles-containing composite materials have short response time and high Kerr nonlinear susceptibility and can be used as ultra-fast optical switchers and limiters.As it was shown in earlier studies of copper nanoparticles embedded in insulator matrices, the tendency was to investigate the influence of MN size and preparation methods [2,3] on their nonlinear refractive index [4], third-order nonlinear susceptibilities and time response [5]. At the same time, such materials possess the enhanced nonlinear absorption properties, in particular negative nonlinear absorption (NNA), i.e. saturated absorption, and positive nonlinear absorption (PNA), i.e. two-photon absorption and/or reverse saturated absorption, especially in the vicinity of the SPR spectral range of the nanoparticles. Recently we have analyzed these nonlinear optical properties as well as the nonlinear refraction in silver-and copper-doped glasses in the spectral ranges far from their SPRs (in UV [6] and IR [7] ranges).In the present note, the results of nonlinear absorption studies regarding the copper nanoparticles embedded in silica glasses by ion implantation and using laser radiation (λ = 532 nm) near the SPR of these MN are presented.
