The fronteer of applications of ultrashort pulse lasers is currently set at the Femtosecond regime, that allow damage free machining of any material. The pulse duration threshold between damage free and processes with residual thermal damage lies between 1 and 50 picoseconds, depending on material characteristics. Pulse duration below 400 femtoseconds ensure the operation in the damage free region.

Refractive microlenses cover a range of 10 µm to 2 mm lens diameters  Refractive microlenses are an interesting alternative for all applications where miniaturization and reduction of alignment and packaging costs are necessary. A refractive microlens refracts the incident light according to Snell's law, similar as large-scale glass lenses do. Refractive microlenses are manufactured in Fused Silica or Silicon or plastic materials, the later case being interesting for anticounterfeit techniques. We have realized the master for high productivity moulding of microlens arrays, targeting drug industry, with sizes down to 30 microns diameter.
