Pulse shaping in laser material processing

Abstract : Ultrafast lasers have gained momentum in material processing technologies in response to requirements for higher accuracy. Minimal energy diffusion and high nonlinearity of interaction indicate the possibility of confining energy on the smallest scales. The possibility of temporal beam manipulation allows adapting the incoming energy rate to the material individual reaction. Optimal energy coupling gives thus the possibility to guide the material response towards user-designed di- rections, offering extended flexibility for quality material processing.
