Open AccessNondestructive inspection of surface nanostructuring using label-free optical super-resolution imaging
Ultrafast laser processing can induce surface nanostructurating (SNS) in most materials with dimensions close to the irradiation laser wavelength. In-situ SNS characterization could be key for laser parameter’...

Open AccessSuper-efficient drilling of metals with ultrafast non diffractive laser beams
A highly efficient drilling process is found in non-transparent metallic materials enabled by the use of non-diffractive ultrafast Bessel beams. Applied for deep drilling through a 200 μm-thick steel plate, th...

Open AccessIn-situ high-resolution visualization of laser-induced periodic nanostructures driven by optical feedback
Optical feedback is often evoked in laser-induced periodic nanostructures. Visualizing the coupling between surfaces and light requires highly-resolved imaging methods. We propose in-situ structured-illumination-...

Optimizing laser-induced refractive index changes in “thermal” glasses
Ultrafast laser radiation usually induces rarefaction and negative refractive index changes in glasses with high thermal expansion. Acting on the laser-induced heat source, tailored intensity envelopes can gen...
