Abstract: We have experimentally determined the threshold energy for filamentation in THEOS-based hybrid silicate nanocomposite materials containing polysaccharides and hyperbranched polyglycidols and the conversion efficiency from the 800-nm femtosecond Ti : sapphire laser output to a supercontinuum in the range 420 – 700 nm. The addition of sodium hyaluronate (polysaccharide) and low concentrations of Au nanoparticles or CdS quantum dots with an average diameter of 3 – 5 nm has been shown to considerably reduce the threshold energy for filamentation and improve the laser output to supercontinuum conversion efficiency.

Keywords: femtosecond laser, filamentation, supercontinuum, conical emission, gold nanoparticles, CdS quantum dots.
