Femtosecond nonlinear absorption of gold nanoshells at surface plasmon resonance. Ros, I., Schiavuta, P, Bello, V., Mattei, G., & Bozio, R. PHYSICAL CHEMISTRY CHEMICAL PHYSICS, 12:13692–13698, 2010. doi abstract bibtex The nonlinear optical absorption of gold nanoshells (Au NSs) of different size, in water, was investigated using open aperture z-scan technique with femtosecond laser pulses at 806 nm. It is found that, in general, NSs behave as saturable absorbers. The level of saturation depends on the Au NSs structure and precisely on the ratio between the core size and shell thickness. The measured values of the nonlinear absorption coefficient show a dependence on both the repetition rate and the pulse energy. An average value of the nonlinear absorption coefficient beta = -4.5 +/- 1.0 x 10(-11) cm W(-1) is obtained from z-scan data of core-shell particles of inner and outer radius 95 and 110 nm, respectively, measured at 20 Hz repetition rate in the energy range 120-300 nJ.
