The development of high-brightness, high-power diode laser sources has opened new markets for direct-diode industrial applications. The output power and beam quality of diode laser systems are now suitable for many tasks that were only possible with solid-state and gas lasers. Much higher wall-plug efficiency, almost maintenance-free operation, long lifetime, compactness and wavelength flexibility make the diode laser a technology of choice for the following applications.
Laser diode based systems are perfectly suited for cutting thin sheet metals, as well as fabrics, plastics, composites, wood and other non-ferrous materials. Since the wavelength of the diode laser can be selected for the maximum absorption of the particular material, the direct diode laser-based process offers high processing speeds with exceptional edge quality.
Welding joints produced by laser equipment at a very high welding speed, and demonstrate exceptional stability, high degree of localization and very low distortion. The aesthetic quality of weld seam surfaces is also superior to any other welding process. Welding of Plastics is of the particular importance as it allows for noncontact welding with low thermal and mechanical load. Plastic housings with built-in electronic components, which could be damaged in conventional processes, can be built. The diode laser can produce almost any wavelength that is strongly absorbed by plastics, and the “flat top” beam profile without intensity peaks. This helps to eliminate local overheating that might damage the components. In addition, diode lasers do not require special absorption layers that may result in surface contamination.
Local and Selective Heat Treating/Cladding
A unique advantage of the diode laser-based surface modification processes is that the output beam can conform to the shape of the surface requiring processing and, thus allow achieving an extremely high throughput. The laser-based process offers superior overall quality, reduced heat input, minimal part distortion and better clad process control. As a result, a finer grain structure and smoother surface morphology leading to better corrosion resistance is produced with diode lasers.

Marking and Printing
Tightly focused diode laser beam can provide a permanent high-contrast mark on different types of metals, plastics, paper, wood and other materials.
