Laserline showcases blue diode lasers at SPIE Photonics West 2025
Laserline is presenting high-power blue diode lasers for processing copper and gold alloys at the Photonics West trade fair. These include the world's first blue diode laser with 6 kW CW output power for highly efficient laser coating processes and additive manufacturing.
At SPIE Photonics West 2025 (January 28-30, San Francisco, booth no. 2149), Laserline will present its comprehensive range of solutions in the field of high-power blue diode lasers. The focus will be on lasers for the industrial processing of copper and gold alloys. Highlights of the trade fair appearance are the first blue lasers with Wavelength Beam Combining (WBC) technology and the world's first blue 6 kW CW industrial diode laser. In addition to its complete portfolio of blue lasers and associated processing optics, Laserline will also be presenting its service and maintenance offering.
High-power blue diode lasers for 3D metal printing and joining
The new blue high-brilliance lasers with WBC technology offer a beam quality of 4 mm∙mrad and output powers of 400 or 800 watts. They are particularly suitable for extremely energy- and material-efficient copper and gold processing in applications such as powder bed-based 3D metal printing and joining. For the first time since Laserline acquired a majority stake in WBC Photonics in summer 2024, the LDFblue 400-wbc and LDFblue 800-wbc diode laser models combine Laserline's proven LDF diode laser technology with WBC Photonics' blade engine technology. This combines the exceptional beam quality of WBC-based lasers with a robust, IoT-ready system architecture known for its high efficiency and stable, spatter-free melt pools.
Blue diode lasers for laser coating processes and additive manufacturing
The second Laserline trade fair highlight, the LDFblue 6000-60, sets new standards for blue diode lasers. With an output power of 6 kW CW and a beam quality of 60 mm∙mrad, it represents the highest power class ever achieved in the blue wavelength spectrum. The LDFblue 6000-60 was specially developed for high-performance applications such as the welding of electrical copper contacts and the additive manufacturing of copper and gold components and achieves a level of performance that was previously reserved exclusively for infrared lasers. In addition to physical and multimedia demonstrations of its systems, Laserline will also be presenting examples of typical process results at its stand. An infrared direct diode laser for drying battery foils will also be on display. This new type of laser is intended to optimize laser drying processes in the roll-to-roll process in the future and thus support climate-friendly and economical series production of lithium-ion batteries.
