The efficacy of plasmonic model to calculate HSFL nanostructure period in Sapphire

In this work, we try to determine all the period of nanostructure subwavelength that can be observed during irradiation by multipulse femtosecond laser in dielectric materials. For this, we use a generalized plasmonic model developed previously to follow the evolution of the periods of the nanostruc...

Description
Summary:In this work, we try to determine all the period of nanostructure subwavelength that can be observed during irradiation by multipulse femtosecond laser in dielectric materials. For this, we use a generalized plasmonic model developed previously to follow the evolution of the periods of the nanostructures on the Sapphire material and their optical properties according to electron-holes plasma excitation and varying the optical spectrum between 300 and 1400 nm. We find a nanostructure area where all the period observed experimentally must be included inside it. This plasmonic model shows its efficiency and its precision on a nanoscale.
