Femtosecond versus picosecond laser machining of nano-gratings and micro-channels in silica glass

Yves Bellouard

The ability of 8 picosecond pulse lasers for three dimensional direct-writing in the bulk of transparent dielectrics is assessed through a comparative study with a femtosecond laser delivering 600 fs pulses. The comparison addresses two main applications: ...

Characterization of optical polarization converters made by femtosecond laser writing

Yves Bellouard

Recently, new types of silica polarization converters fabricated by femtosecond lasers have been introduced. These devices use spatially arranged nanogratings found under certain femtosecond laser exposure conditions in fused silica to create arbitrary pol ...

Femtosecond Laser Processing of Active and Passive Devices for bio-MEMS

Yves Bellouard

Femtosecond laser processing of glass has been proven to be an efficient tool for fabricating waveguides and microchannels. Here we show that monolithic integration in bio-Micro- Electro-Mechanical-Systems can be pushed forward by introducing additional fu ...

Nanograting Orientation Influence on Stress Induced by Femtosecond Laser in Fused Silica

Yves Bellouard

Under certain conditions, femtosecond lasers can be used to introduce self-organized nanogratings in the bulk of fused silica. Here, we report that the nanogratings orientation influences the induced stress distribution around laser affected zones. ...
