Abstract

Research into multi-photon absorption of plasmonic metal and dielectric nanoparticles have gained a lot of interest recently because information on the multi-photon absorption coefficient is necessary for modeling and designing these nanoparticles for application in biolabelling and deep tissue imaging. Here we present Z-scan measurement results on gold thin films by using femtosecond pulsed laser at wavelengths in near and mid infra-red range (1 μm – 2 μm).
