To use or not to use (direct laser interference patterning), that is the question

Abstract

Direct Laser Interference Patterning (DLIP) has shown to be a fabrication technology capable of producing large area periodic surface patterns on almost any kind of material. The produced structures have been used in the past to provide surfaces with new enhanced properties. On the other hand, the industrial use of this technology is still at the beginning due to the lack of appropriate and affordable systems, especially for small and medium enterprises. In this paper, the use of DLIP for the fabrication of periodic structures using different structuring strategies and optical concepts is discussed. Different technological challenges are addressed

Direct laser interference patterning and ultrafast laser-induced micro/nano structuring of current collectors for lithium-ion batteries

“…At laboratory scale, a coherent laser beam is split into two or more sub-beams by using a beam splitter which are later overlapped on the surface. The number of used laser beams permit to control the intensity distribution of the interference pattern [8]. A two-beam configuration enables to produce a line-like interference pattern as shown in figure 1 a) The periodicity Λ of line-like structures can be adjusted by varying the angle α between two sub-beams as well as the wavelength λ:…”

“…Recently surface structuring speeds up to 0.7 m²/min could be reached using a 180W IR laser [8]. In this study, the DLIP structuring process was performed for all experiments applying a laser wavelength of 1064 nm and a pulse duration of 10 ps.…”

Combining Thickness Reduction and Light Trapping for Potential Efficiency Improvements in Perovskite Solar Cells

“…According to Ref. the DLIP manufacturing cost in 2015 was approximately 3.62 $ m −2 for processing TCO materials taking into account one operator working 52 weeks, 39 h a week with 100% overhead and the cost necessary for acquiring the equipment distributed in 3 years at maximum fabrication speed. Based on these assumptions we envisage two distinct scenarios, which we define as pessimistic and optimistic.…”

High‐Speed Surface Structuring of Polycarbonate Using Direct Laser Interference Patterning: Toward 1 m2 min−1 Fabrication Speed Barrier

“…In order to fabricate periodic patterns on technical components, different technologies are available. However, the challenge is not just to be capable to produce periodic patterns in the micrometer and sub‐micrometer scale but to fabricate them at both low cost and high throughput . In Lasagni et al, different mask‐less fabrication methods were compared.…”
