Impact of Pre-Patterned Structures on Features of Laser-Induced Periodic Surface Structures

Abstract

The efficiency of light coupling to surface plasmon polariton (SPP) represents a very important issue in plasmonics and laser fabrication of topographies in various solids. To illustrate the role of pre-patterned surfaces and impact of laser polarisation in the excitation of electromagnetic modes and periodic pattern formation, Nickel surfaces are irradiated with femtosecond laser pulses of polarisation perpendicular or parallel to the orientation of the pre-pattern ridges. Experimental results indicate that for polarisation parallel to the ridges, laser induced periodic surface structures (LIPSS) are formed perpendicularly to the pre-pattern with a frequency that is independent of the distance between the ridges and periodicities close to the wavelength of the excited SPP. By contrast, for polarisation perpendicular to the pre-pattern, the periodicities of the LIPSS are closely correlated to the distance between the ridges for pre-pattern distance larger than the laser wavelength. The experimental observations are interpreted through a multi-scale physical model in which the impact of the interference of the electromagnetic modes is revealed.

Controlling LIPSS formation on Ni surface using near-infrared laser beam and its low-order harmonics

“…The periodic structure generated by using only the fundamental wavelength (figure 3(a)) resulted in a surface periodicity of Λ ∼ = 850 nm, which is around 0.82% of the incident beam wavelength. Such reduced surface periodicity to the incident beam wavelength ratio on Ni was reported earlier in [27,[45][46][47][48][49].…”

Nanotubular Arrayed LIPSS Achieved with Femtosecond Bessel Beam on Silver Surface for SERS-Based Multiple Explosive Sensing

“…Furthermore, in the case of BB ablation, we accomplish several advantages in terms of LIPSS formation, which are believed to perform momentously regarding the possible formation of nanotubular arrayed LIPSS. Maragkaki et al . have determined an improved efficacy in electromagnetic mode coupling by employing prepatterned surfaces.…”
