Laserline At LASER World Of Photonics

Laser World of Photonics 2022: Laserline presents the world's first blue diode laser with 3 kW CW output power

High power cladding with 45 kW IR diode laser as the second focus
Laserline's appearance at the Laser World of Photonics 2022 is all about technological innovation. The world's first blue diode laser with 3 kW CW output power and a new high-power cladding solution using a 45 kW IR diode laser, developed in cooperation with the Fraunhofer IWS, will be presented.

Laserline is presenting the world's first blue diode laser with 3 kW CW output power at the Laser World of Photonics 2022 (April 26 to 29 in Munich). Designed especially for welding, coating and additive manufacturing of copper components, it marks another milestone in the performance development of blue high-power diode lasers. The second focal point of the trade fair presence is a new high-power cladding solution based on a 45 kW IR diode laser. It was developed in cooperation with the Fraunhofer Institute for Material and Beam Technology IWS and is intended to optimize the industrial coating of components at risk of wear and corrosion.

More effective and energy-efficient copper processing with blue 3 kW diode laser
After Laserline presented the world's first blue CW diode laser with up to 1 kW CW output power in 2019 and was able to increase the power to 2 kW just one year later, the blue 3 kW diode laser shown in Munich embodies the highest power class of industrial lasers in blue to date wavelength spectrum. The new laser works like the 1 and 2 kW Laserline diode lasers with a wavelength of around 445 nm. This spectral range is absorbed by non-ferrous metals such as copper and gold much better than infrared radiation, which, among other things, enables heat conduction welding of thin copper components close to the surface as well as more energy-efficient and climate-friendly machining processes overall . The increase in CW output power to 3 kW now opens up additional application options. In the case of joining and coating processes, far faster welds and higher application rates can be achieved. When deep-penetrating electrical conductors such as copper hairpins, for example, even larger cross-sections can be mastered with moderate heat input using blue lasers alone. Where hybrid blue and infrared laser joining solutions are still required, less infrared energy is required than in the past, reducing operating costs and CO2 balance of the applications noticeably optimized. In addition, the new laser power class enables more efficient additive manufacturing of large and high-volume copper components. At the Laserline booth, these new application options will be explained in detail and demonstrated using various welding and coating samples.

Cladding with a laser power of up to 45 kW: higher order rates – larger quantities
The high-power cladding solution presented represents the next expansion stage of a build-up welding process that has already been successfully implemented by the Fraunhofer IWS using Laserline IR diode lasers with an output power of 20 kW and which in some cases even exceeds the build-up rates in PTA cladding (Plasma Transferred Arc). . As the first process of its kind, it enables wear and corrosion protection coatings on large components such as power plant components, but also on brake discs, hydraulic cylinders or plain bearings, to be produced at low cost and suitable for series production. The entry into the use of a higher diode laser power class with an output power of up to 45 kW further increases the efficiency and productivity of the process and makes higher application rates possible with reduced process costs.
