Lasers for material processing

The selection of the best laser for a given application is a common problem of laser users. However, a direct relationship between laser intrinsic characteristics and a potential application, risks to make the laser source selection process unilateral and partially mistaken. In fact, the best processing technology for a given application must be chosen. Therefore, the present paper proposes an indirect, more realistic selection process. This process starts from a general laser application definition. Then, it passes through the analysis of the needed laser beam--workpiece material interaction and of the necessary laser technological system. Finally, the selection process ends with the laser processing technology definition, where the choice of the most suitable laser source becomes in fact possible.
