The presentation explains the different methods of generating (via additive manufacturing) and cladding products using diode lasers. Various samples are shown and discussed. In the second part of the presentation, the principle of laser hardening and its advantages compared to conventional methods are explained and demonstrated with examples.

In addition, the presentation provides updates on the latest developments in diode laser technology, and explains why an increasing number of applications can be performed with these systems. Diode lasers are more efficient than CO2, fibre and disk lasers, and therefore face brilliant outlook in the market, underlined by several independent experts.

Laser beam shaping is an established method to adapt the power distribution to the specific requirements of a particular laser application. The first applications to use beam shaping are laser surface treatment applications, such as laser heat treatment. Dynamic beam shaping is more flexible compared to static beam shaping, so it allows a precise adjustment of laser power distribution, even during laser processing. Nowadays, dynamic beam shaping focuses more on narrow gap welding, the welding of hard-to-weld materials like aluminium alloys, and on thick plate cutting. Fast galvanometer scanners are currently used to provide appropriate beam shaping, but new techniques such as microelectromechanical system (MEMS) scanners are on the way.

Effective process control is dependent upon careful and precise monitoring of the laser power. In addition to exploring the role of laser power monitors in improving process stability, this white paper presents a solution for the gap that exists within detectors' power range and wavelength range.

Countless applications rely on laser processing systems driven by highly dynamic galvo scanners, which precisely position the laser beam onto workpieces. A new patented digital encoder has succeeded in breaking past current dynamic-performance limitations – while simultaneously retaining the highest precision for high-dynamics applications.
