Open AccessMultispectral in-line hologram reconstruction with aberration compensation applied to Gram-stained bacteria microscopy
In multispectral digital in-line holographic microscopy (DIHM), aberrations of the optical system affect the repeatability of the reconstruction of transmittance, phase and morphology of the objects of interes...

Tailoring the surface morphology of Ni at the nanometric scale by ultrashort laser pulses
Ultrafast-laser irradiated surfaces are self-organizing systems that form intricated micropatterns and nanopatterns. Different shapes of randomly and periodically dispersed nanostructures emerge from a homogen...

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-...

Experimental measurements and behavioral modeling of an electrostatically actuated bi-axial micromirror
Recent developments in micro-electro-mechanical systems and micromachining technologies have made possible the development and integration of micromirrors that can be employed for a number of consumer applicat...
