Direct Laser Interference Patterning (DLIP) is a laser processing method that provides a tool for creating a wide field of functional surfaces. In the present work, the generation of antibacterial surfaces on stainless steel is shown with a high power capable DLIP setup. The used laser was an ultrafast laser with a wavelength of 1030nm and a pulse duration of eight picoseconds. Two different topographies were produced, which were generated with two different polarization orientation of the laser. Both topographies were investigated in their antibacterial behavior. The employed method for assessing the bacterial retention is based on ISO standards for measurement of antibacterial performance. The resulting topographies shows a retention of up to 99,8% for E. Coli and up to 79.1% for S. aureus bacteria.
