Nonlinear Optical Properties of Biosilicate Nanocomposite Materials

Article Preview

Abstract:

The transmission of the femtosecond laser pulses by new biosilicate nanocomposite materials has been experimentally investigated. The strong nonlinear optical properties of these nanocomposite structures have been revealed in spectral characteristics of transmitted ultrashort pulses. The shape of transmitted spectrums through new nanocomposite biomaterials demonstrates major changes indicating the broadening with formation a strong anti Stokes component in the output spectrum with generation of supercontinuum spectra. The carried out studies have showed that the optical nonlinearity of new nanocomposite materials can be regulated by trace amounts of Au or CdS nanoparticles.
