Ultra-fast writing of self-organized bubble networks using femtosecond laser exposure in the cumulative regime

Yves Bellouard, Max-Olivier Hongler

Femtosecond pulses focused in glass substrate induces various modifications in the material depending on the fluence level and laser exposure conditions. Upon increasing pulse energies above the energy threshold for non-linear absorption, femtosecond laser ...

Optofluidic lab-on-a-chip for rapid algae population screening

Yves Bellouard

The rapid identification of algae species is not only of practical importance when monitoring unwanted adverse effects such as eutrophication, but also when assessing the water quality of watersheds. Here, we demonstrate a lab-on-a-chip that functions as a ...

Polymer micro-molding of femtosecond laser micromachined substrates

Yves Bellouard

Micro-molding can be used for the cost-effective fabrication of elements such as active or passive components in MEMS devices, hydrophobic surfaces, cell-growth scaffolds or optical components such micro-lens arrays and gratings. This method is also partic ...

On the use of shape memory alloy thin films to tune the dynamic response of micro-cantilevers

Yves Bellouard, Xi Wang

We investigate the effect of martensitic phase transformations on the dynamic response of commercial AFM silicon cantilevers coated with shape memory alloy (SMA) thin films. We propose a simple thermo-mechanical model to predict the phase transformation. W ...
