Femtosecond pulse

Femtosecond laser pulses are used for the ablation of metals and dielectrics (2D and 3D structures), structural changes of materials, optical changes or mechanical processing such as cutting, drilling or milling in order to replace mechanical machining tools. Femtosecond pulse shaping is a powerful technique used in ultrafast optics for the generation of ultrashort (femtosecond) laser pulses with complex temporal shapes. A commonly used approach is Fourier transform pulse shaping in which the spectral components of a broadband pulse are spatially separated so that they can be manipulated individually to give desired pulse shape when recombined. In the specialized literature, "ultrashort" refers to the femtosecond (fs) and picosecond (ps) range, although such pulses no longer hold the record for the shortest pulses artificially generated. Indeed, x-ray pulses with durations on the attosecond time scale have been reported.

A central building block for generating femtosecond light pulses are lasers. Only within two decades after the invention of the laser the duration of the shortest pulse shrunk by six orders of magnitude from the nanosecond regime to the femtosecond regime. Nowadays femtosecond pulses in …
