    • Ablation and optical third-order nonlinearities in Ag nanoparticles 

      Torres Torres, Carlos; Perea López, Néstor; Reyes Esqueda, Jorge Alejandro; Rodríguez Fernández, Luis; Crespo Sosa, Alejandro; Cheang Wong, Juan Carlos; Oliver G., Alicia (Dove Press Ltd, 2010)
      "The optical damage associated with high intensity laser excitation of silver nanoparticles (NPs) was studied. In order to investigate the mechanisms of optical nonlinearity of a nanocomposite and their relation with its ...

    • Coexistence of two-photon absorption and saturable absorption in ion-implanted platinum nanoparticles in silica plates 

      Torres Torres, Carlos; Bornacelli, J.; Can-Uc, Bonifacio Alejandro; Silva Pereyra, Héctor Gabriel; Rodríguez Fernández, Luis; Ávalos Borja, Miguel; Labrada Delgado, Gladis Judith; Cheang Wong, Juan Carlos; Rangel Rojo, Raúl; Oliver y Gutiérrez, Alicia María (Optical Society of America, 2018)
      "Platinum nanoparticles were nucleated in a high-purity silica matrix by an ion-implantation method. The third-order nonlinear optical response of the samples was studied using femtosecond pulses at 800 nm with the z-scan ...

    • Superlinear photoluminescence by ultrafast laser pulses in dielectric matrices with metal nanoclusters 

      Bornacelli, J.; Torres Torres, Carlos; Silva Pereyra, Héctor Gabriel; Labrada Delgado, Gladis Judith; Crespo Sosa, Alejandro; Cheang Wong, Juan Carlos; Oliver y Gutiérrez, Alicia María (Nature Publishing Group, 2019)
      "An intense photoluminescence emission was observed from noble metal nanoclusters (Pt, Ag or Au) embedded in sapphire plates, nucleated by MeV ion-implantation and assisted by an annealing process. In particular, the ...
