Bessel beam generated LIPSS on NiTi wires
Ultrashort laser pulses are used to generate laser-induced periodic surface structures (LIPSS). To generate LIPSS on small, confined surfaces, the laser source must be focused to a small spot diameter. In contrast to the commonly used high numerical aperture objectives, we present a Bessel beam based approach to generate LIPSS covered lines. The setup convinces with a large depth of field. The applicability of this method is demonstrated by patterning the cladding surface of nickel-titanium wires.
The work is presented on the cover of the journal Applied Physics A.
