Abstract:
Femtosecond laser structuring of dielectrics is an urgent problem for the creation of optical elements. In this work, we performed femtosecond laser nanostructuring of the calcium fluoride surface with the formation of self-organizing periodic gratings with subwavelength periods of the order of 200 and 350 nm. During the work, the dependence of the period of the structures on the wavelength of laser radiation was established, which was confirmed by the simulation results. The structures show a decrease in transmission over the entire visible range, predominantly due to diffraction and light scattering.
Keywords:
direct laser recording, femtosecond laser pulses, surface functional nano- and micro-optical structures, diffraction.
