Abstract
This report introduces a recently development method for the direct fabrication of 2D and 3D structures. The technique involves the modulation of the laser beam intensity by generating interference pattering. By using high power lasers it is possible to directly modify the materials surface obtaining micro- and submicrometer periodic arrays with controlled spatial modulation. Some examples of fabricated structures on metals, polymers well as ta-C layer are discussed.
