“…The first treatments of organic matrices by irradiation with a UV laser were published in the 1980s. [ 10,11 ] Taking into account the material absorption coefficient, [ 12 ] the treated area of the material is of the order of several multiple wavelengths. [ 13‐15 ] It is, thus, possible to precisely control the ablation depth by the exposure time or the number of pulses.…”

To understand both chemical and anchoring aspects of Al adhesion, the poly‐ether‐ether‐ketone (PEEK) surface was plasma‐textured before being coated. The practical adhesion was compared with that obtained by laser texturing. The surfaces and assemblies were characterized by scanning electron microscopy, atomic force microscopy, surface free energy determination, and pull‐off tests. Patterning processes increase Al adhesion. O2 plasma appears to be the most efficient through a texture assigned to the chemical erosion, whereas Ar plasma mostly induces material etching with thermal effects altering the PEEK crystallinity. With low‐pressure plasmas, this texturing can be added to the chemical functionalization to further increase the adhesion.

“…It is virtually impossible for a femtosecond-scale process (or even picosecond) such as the ultrashort laser-pulse-induced damage threshold mechanism described above to explain the accumulative process which occurs at the scale of milliseconds. A general comprehensive theory has yet to be developed, but qualitatively, the decrease in the damage threshold with multi-pulse irradiation was attributed to the accumulation of laser-induced chemical and structural changes of the material, plastic deformation of the surface [10, 14] , thermal or bulk photo-thermal model [35] . Other models [36–38] explain the incubation effect [39] by accumulation of occupied defect and mid-gap trap states during the pulse train, since the relaxation of electrons from defect states to the valence band is on a time scale of milliseconds.…”

We developed a systematic experimental method to demonstrate that damage threshold fluence (DTF) for fused silica changes with the number of femtosecond laser (800 nm, 65 ± 5 fs, 10 Hz and 600 Hz) pulses. Based on the experimental data, we were able to develop a model which indicates that the change in DTF varies with the number of shots logarithmically up to a critical value. Above this value, DTF approaches an asymptotic value. Both DTF for a single shot and the asymptotic value as well as the critical value where this happens, are extrinsic parameters dependent on the configuration (repetition rate, pressure and geometry near or at the surface). These measurements indicate that the power of this dependence is an intrinsic parameter independent of the configuration.
