Direct volume variation measurements in fused silica specimens exposed to femtosecond laser

Yves Bellouard

We introduce a new method to investigate localized volume variations resulting from laser exposure. Our method is based on the measurement of fused silica cantilevers deflection from which we calculate the effective stress and density variation in laser-af ...

The Femtoprint Project

Yves Bellouard, Reymond Clavel, Jean-Marc Breguet

The Femtoprint project, a European project, aims at demonstrating the use of low-energy laser pulses (i.e. below the ablation threshold) to manufacture monolithically integrated devices including optofluidic, optomechanical and photonic devices. The longer ...

Femtoprint: A femtosecond laser printer for micro- and nano-scale systems

Yves Bellouard, Reymond Clavel

The Femtoprint project uses femtosecond lasers to develop a printer for micro-/nano- scale systems. Femtoprint provides a large community of users with the capability of producing their own micro-systems, in a rapid-manner without the need for expensive in ...

On the role of the scanning line density on the etching of fused silica specimens exposed to femtosecond lasers pulses

Yves Bellouard

Fused silica (a-SiO 2) exposure to low-energy femtosecond laser pulses (below ablation threshold) introduces a local increase of the HF etching rate. This property has been used to fabricate a variety of structures ranging from simple fluidic channels to m ...

Density variation in fused silica exposed to femtosecond laser

Yves Bellouard

Fused silica (a-SiO2) exposure to low-energy femtosecond laser pulses leads to interesting effects such as a local increase of etching rate and/or a local increase of refractive index. Up to now the exact modifications occurring in the glass matrix after e ...

Optofluidic microdevice for algae classification: a comparison of results from discriminant analysis and neural network pattern recognition

Yves Bellouard

The early detection of changes in the level and composition of algae is essential for tracking water quality and environmental changes. Current approaches require the collection of a specimen which is later analyzed in a laboratory: this slow and expensive ...

Design of a miniature laser scanning head for high-bandwidth, low-amplitude beam steering

Yves Bellouard, Reymond Clavel

In laser micro-manufacturing, one of the challenges is to achieve fast scanning speed for fast fabrication of complex 3D microstructures. For microstructures with nanoscale features, it is often desirable to steer laser beams from a few microns to a few te ...

On the bending strength of fused silica flexures fabricated by ultrafast lasers [Invited]

Yves Bellouard

This paper reports on the mechanical properties of fused silica flexures manufactured by a two-step process combining femtosecond lasers exposure below the ablation threshold and chemical etching. Flexural strengths as high as 2.7 GPa were measured, demons ...

Femtosecond-laser generation of self-organized bubble patterns in fused silica

Yves Bellouard, Max-Olivier Hongler

By continuously scanning a femtosecond laser beam across a fused silica specimen, we demonstrate the formation of self-organized bubbles buried in the material. Rather than using high intensity pulses and high numerical aperture to induce explosions in the ...
