Paper Abstract

The shapes of initially spherical Ag nanoparticles in glass were permanently changed by fs laser irradiation. This shape transformation of the nanoparticles results in an optical dichroism of the material, strongly depending on the actual irradiation parameters such as intensity, number of pulses per irradiated spot and laser wavelength. The proposed technique allows modifying the optical properties of glass containing metallic nanoparticles and can be used for the production of dichroic or polarizing microstructures in the visible and near infrared region with high polarization contrast.
