Abstract

We study the total reflectance of femtosecond laser-induced periodic surface structures (FLIPSSs) in the UV, VIS, and IR wavelength ranges. We find that FLIPSSs are an effective technique for controlling optical properties of metals in the UV, VIS, and NIR spectral regions. In contrast to previous studies of FLIPSSs produced over an area of only a single irradiation spot on metals, we demonstrate that FLIPSSs can be produced over an extended area by scanning laser beam. This FLIPSS technique has potential applications in photonics, plasmonics, optoelectronics, thermal radiation sources, and bio-optical devices.
