Abstract

New industrial applications of femtosecond lasers are continuously emerging in various industrial sectors: health, production, energy, transport. Fiber delivery of femtosecond pulses and power is a key enabling technology for opening industrial application fields much wider: conventional micromachining stations typically based on ultrastable and ultraheavy granite tables are avoided and the femtosecond laser is coupled into a flexible light guide instead. Ultraprecise machining processes can such be displaced far from the femtosecond laser source and coupled to moving axes or robot systems. Here, we report on a femtosecond fiber delivery system for industrial applications. In a first demonstration, the delivery system is coupled to a Satsuma industrial femtosecond laser with average output power of more than 20 W and pulse energy up to 60 μJ. Polarization control allows addressing any kind of micromachining applications, also those sensitive to the polarization state incident on the workpiece. Coupling of the fiber delivery system to a robot system and the nanotexturing by LIPSS will be here reported. Comparisons of the obtained results with conventional micromachining applications using free beam propagation are drawn and future perspectives to higher laser powers and energies as well as to wavelength converted femtosecond pulses discussed.
