In this work, we report about the fabrication of textured aluminium surfaces using Direct Laser Interference Patterning with picosecond (70 ps) and femtosecond (400 fs) laser pulses as well as their wetting properties. The structuring process was performed by varying the pulse numbers from 25 to 250, resulting in various depths ranging from 0.9 μm to 6.8 μm. The wetting analysis shows that the ps-patterned surfaces exhibit long-term superhydrophobic characteristics (at 21 °C and 16 % air humidity). Differently, for the fs-processed substrates, a hydrophobic character was firstly observed, which later (after 16 days) dropped to contact angles similar as the untreated material.

Laser Induced Periodic Surface Structuring (LIPSS) is a powerful tool for creating submicrometric features on large surfaces in an up-scalable and industrial way. In order to control the process and reach a sufficient uniformity for some applications a careful attention must be paid to the control of the laser beam parameters like its polarization, stability and shape. A uniform beam shape is mandatory in some cases. Although some demonstrations of beam shaping with high power handling optical components have been made, there is not much reported regarding the use of SLM (Spatial Light Modulator) for beam shaping of ultrashort pulses. In the current work we show the possibility to use SLM with different type of laser sources, including a femtosecond system delivering up to 1 mJ per pulses.
