Periodic Pattern Formation of Intermetallic Phases with Long Range Order by Laser Interference Metallurgy

Abstract

Laser Interference Metallurgy is a newly developed method which allows the creation of periodic patterns with a well defined long‐range order on metallic surfaces. This article provides three fundamental aspects to understand the surface structuring process: the formation of complex periodical structures in metallic thin films by using three laser beams with variable intensities; the structuring of bi‐layered metallic films, and the possibility of the formation of periodical intermetallic structures.

Micro/Nano Fabrication of Periodic Hierarchical Structures by Multi‐Pulsed Laser Interference Structuring

“…The lateral period of the interference fringes is a function of the incident wavelength (k) and the angle between the laser beams (h) as described in Equation 1. [3] P k= 2 sin h=2…”

Macroscopic 2D Design of Micro/Nano Grain Architectures by Laser Interference Metallurgy

“…2f). Further details of the thermal simulations can be found in [10,13]. The ring in the (111) -pole figure at ψ ~ 70° is a contribution of other crystallographic equivalent {111}-planes.…”

Direct laser interference patterning of polystyrene films doped with azo dyes, using 355nm laser light

“…In this study, we used a simple method for developing microstructures on doped PS, direct Laser Interference Patterning (DLIP). DLIP permits the fabrication of repetitive 1D and 2D patterns and microstructures by direct irradiation of the sample surface with coherent beams of light [26,27]. Furthermore, we show that it is possible to produce microstructures with DLIP lines-type by illumination of a single pulse suitably doped PS with at wavelength of 355 nm.…”
