Ultrafast laser-induced self-organized conical micro/nano surface structures and their origin

Fabrication of Micro/Nano Structures on Metals by Femtosecond Laser Micromachining

“…The effect of polarization on LIPSS formation at a fluence of 1 J/cm 2 has been studied for Si. It was observed that the number of pulses needed to form LIPSS with circular polarization (10-30 pulses) is higher than that of linearly polarized laser light (5-15 pulses) [109]. The effect of polarization was also studied on Tungsten using linearly polarized light, elliptically polarized light, as well as left and right circularly polarized light [103].…”

“…We want to emphasize here that the self-organization in laser micromachining process is characterized by structures of dimensions smaller than the size of the effective laser beam diameter [12,79,87,89,109,117]. The feature sizes of the laser-inscribed surface structures are approximately equal to or larger than the effective beam diameter.…”

Theoretical Evaluation of the Temperature Field Distribution in the Silicon Periodic Nanostructures During Thermal Annealing

“…Now, creation of periodic surface structures and properties of these structures are analyzed in great scale with various methods [8][9][10][11] for using in practical work [12][13][14][15].…”

Surface nano-texturing of silicon by picosecond laser irradiation through TiO2 nanotube arrays

“…Nayak and Guptha [4] investigated the origin and subsequent evolution of self-organized conical micro/nanostructures on silicon surface upon irradiation of multiple ultrafast laser pulses in the gaseous environments of SF 6 and Helium. Trtica et al [5] reported laser-induced periodic surface structures (LIPSS) with both micrometer and nanometer scale ripples, by a 532 nm picosecond Nd:YAG laser on crystalline silicon with different laser irradiation fluences of 0.7, 1.6 and 7.9 J/cm 2 .…”
