Abstract
In this paper the processing of a fiber reinforced plastic consisting of glass fibers embedded in polypropylene with ultra short laser systems is shown. Focus of the study is on the dependence of working wavelength (1064 nm, 532 nm and 355 nm) and pulse duration (500 fs to 10 ps) on the laser ablation characteristic of the treated material. Depending on the energy density and the material properties, two different process regions could be identified.
