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 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 5,000 Laserline diode lasers have been delivered worldwide. Laserline currently employs 360 people and has international subsidiaries on the American continent (USA, Brazil) and in Asia (Japan, China, South Korea) as well as sales partners in Europe (France, Italy, Great Britain) and in the Asia-Pacific region (India, Singapore, Taiwan, Australia). Laserline diode lasers can be found in a wide variety of different sectors and application areas. Typical application areas are classical forms of metal processing, as welding, brazing, hardening or softening, as well as realization or repair of coatings. Furthermore, Laserline diode lasers have been established for plastic welding and additive manufacturing (metal 3D print) or welding of fiber composites. With the worldwide first blue cw high power diode laser (450 nm), Laserline now also enables controlled heat conduction welding of copper and other highly reflective materials.
