“…They can be used for creating more complex, programmable, and adaptive patterns, but require significantly higher investment and the SLMs can be damaged, in particular when applying high energy densities. They can also be combined with a Schwarz-lens element in order to obtain larger interference angles [19].…”

This manuscript introduces a comprehensive overview in the field of Direct Laser Interference Patterning (DLIP) with a focus on its evolution over the last years, its current status, and the emerging challenges it faces. Starting with the emerging stages of DLIP, attention will be directed towards the role played by the development of innovative optical systems, which have been instrumental in pushing the boundaries of precision and control. Examples of surface functionalization achieved through DLIP techniques are also showcased, emphasizing the transformative impact that DLIP has had across various industries, from the enhancement of material properties to the facilitation of new functionalities. Furthermore, consideration will be given to the evolving landscape of inline monitoring approaches within DLIP. These monitoring techniques are poised to address the intricate challenges associated with real-time quality control and process optimization in DLIP applications.

“…Experiments are performed utilizing 1D and 2D DLIP combined with SP and DP irradiation. Several techniques have been introduced in order to realize DLIP, including the use of a grating, a prism and a lens to combine the laser beams, as well as a Spatial Light Modulator (SLM) [51]. Nevertheless, only some of these configurations are suitable to apply with femtosecond pulses.…”

Direct laser Interference Patterning (DLIP) with ultrashort laser pulses (ULP) represents a precise and fast technique to produce tailored periodic sub-micrometer structures on various materials. In this work, an experimental and theoretical approach is presented to investigate the previously unexplored fundamental mechanisms for the formation of unprecedented laser-induced topographies on stainless steel following proper combinations of DLIP with ULP. DLIP is aimed to determine the initial conditions of the laser-matter interaction by defining an ablated region while double ULP are used to control the reorganisation of the self-assembled laser induced sub-micrometer sized structures by exploiting the interplay of different absorption and excitation levels coupled with the melt hydrodynamics induced by the first of the double pulses. A multiscale physical model is presented to correlate the interference period, polarization orientation and number of incident pulses with the induced morphologies. Special emphasis is given to electron excitation, relaxation processes and hydrodynamical effects that are crucial to the production of complex morphologies. Results are expected to derive new knowledge of laser-matter interaction in combined DLIP and ULP conditions and enable enhanced fabrication capabilities of complex hierarchical sub-micrometer sized structures for a variety of applications.
