About us

Laserline is one of the pioneers in diode laser technology, and played a significant role in achieving a breakthrough with this laser type. Founded in 1997, the German company grew within only a few years to becoming an international leading developer and manufacturer of diode lasers for industrial applications. As of today, about 6,000 Laserline diode lasers have been delivered worldwide. Laserline has international subsidiaries on the American continent and in Asia as well as sales partners in Europe and in the Asia-Pacific region. Laserline diode lasers can be found in a wide variety of different sectors and application areas. Typical application areas are welding of steel and aluminum, cladding, additive manufacturing as well as brazing and heat treatment. With the worldwide first blue cw high power diode laser (445 nm), Laserline now also enables controlled heat conduction welding of copper and other highly reflective materials.

Products & Services

Laserline, international leading developer and manufacturer of diode lasers, makes laser systems for industrial material processing. Laserline presents the world’s first blue diode laser with 4 kW CW output power. It was especially designed for welding, cladding and additive manufacturing of copper components. It is a further milestone in the power development of blue high-power diode lasers. At the compact LDM laser systems, Laserline shows off a product generation that offers 50 percent more laser power in a 7 RU - 19" rack mount system. Up to 10 kW laser power in less than 100 liters installation space sets a standard for high power lasers and opens up more possibilities for system integration. With the LDF series Laserline is setting the benchmarks for high power diode lasers. 25 kW laser power in less than one square meter footprint. Now even at high beam qualities: 8 kW out of a 600 µm fiber at NA 0.1 in a compact and mobile system configuration.

Diode Laser System LDF VG6 – The modular laser platform

Laserline is the international leading manufacturer of laser diodes for industrial materials processing and sets a new benchmark for high power diode lasers: The modular LDF VG6 series is versatile in use, offers 25 kW laser power in less than one square meter footprint and an electrical efficiency up to 50 percent – even at high beam qualities. Whether power, internal or external cooling system or system interfaces: The LDF series can be individually configured to changing requirements.

Diode Laser System LDM – compact, powerful and reliable

Many laser operators require compact but reliable systems that also deliver high laser power. This balancing act is perfectly achieved by the Laserline LDM diode laser series that sets a new dimension benchmark with a 7 RU-19” (10,000 W diode laser) or an even smaller 5 RU-19” (4,000 W diode laser) rack module. The LDM system combines laser head, power supply of the diodes, monitoring-controller as well as a cooling system and is ideal for welding, hardening or mobile repair welding.

Laserline blue - Diode Lasers for Processing of High Reflective Metals

Laserline’s blue high power diode laser series revolutionizes the processing of copper, gold and its alloys in various ways. With approximately 445 nm, these lasers offer the ideal wavelength for the laser processing of highly reflective metals. Multiple times higher absorption allows significantly lower intensities and larger laser spots. Up to 4 kW cw of available laser power supports both – controlled heat conduction welding as well as keyhole welding processes.
