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 AccessMultiscale electronic and thermomechanical dynamics in ultrafast nanoscale laser structuring of bulk fused silica
We describe the evolution of ultrafast-laser-excited bulk fused silica over the entire relaxation range in one-dimensional geometries fixed by non-diffractive beams. Irradiation drives local embedded modificat...

Open AccessHigh fidelity visualization of multiscale dynamics of laser-induced bubbles in liquids containing gold nanoparticles
Cavitation in pure liquids and in liquids containing nanoparticles enables applications in mechanics, bio-medicine, and energy. Its evolution carries a significant interest. We describe the multiscale dynamic ...

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-...
