O-FIB: Far-field-induced near-field breakdown for direct nanowriting in an atmospheric environment

Lasers are becoming one of the dominant tools in current manufacturing industry. Much effort has been devoted to improving processing accuracy, and spatial resolutions as low as micrometers have been achieved in laser cutting, welding, marking and stereolithography in an atmospheric environment. The femtosecond laser (fs-laser) is a particularly promising approach from this point of view, in addition to its three-dimensional (3-D) processing capability and broad-spectrum material usability.
