Laser processing of optically transparent or semi-transparent, brittle materials is finding wide use in various manufacturing sectors. For example, in consumer electronic devices such as smartphones or tablets, cover glass needs to be cut precisely in various shapes. The unique advantage of material processing with femtosecond lasers is efficient, fast and localized energy deposition in nearly ...

1 Fundamentals A femtosecond laser can fully ionise almost any solid material with greatly reduced recast, microcracks and heat-affected zone (Jiang and Tsai, 2003). Compared with a long pulse, a femtosecond pulse in some aspects fundamentally changes laser materials interaction mechanisms. New phenomena induced by femtosecond lasers lead to a new

The interaction of femtosecond laser pulses with transparent materials relies on non-equilibrium process with photon beams and this provides new access to create materials and micro-devices that cannot be obtained by other means. Understanding of the physical mechanisms of many induced phenomena is extremely challenging.

Nanostructured regular patterns on silicon surface are made by using femtosecond laser irradiations. This is a novel method that can modify the surface morphology of any large material in an easy, fast, and low-cost way.
