Santa Clara, California June 20, 2019 - As the international top developer and manufacturer of diode lasers for industrial material running, Laserline proceeds to develop its outstanding market position. With prompt effect, a new high power laser series LDMblue has become obtainable with up to 1 kW output power. These lasers function at 450 nm wavelength and are the first industrial diode lasers competent of making a controlled heat conduction welding of really reflective nonferrous metals such as copper and gold. These lasers offer new and more efficient manufacturing options, specifically with joining of thin copper for illustration used in battery production for electric vehicles. Finely tuned power rules within milliseconds and extraordinary calm melt pools will make sure smooth-seam areas with excellent electrical conductivity. Thereby rendering the laser systems interesting as well for design-oriented applications in visible areas. Furthermore, the diode lasers of the LDMblue series have also been successfully analyzed in cladding and additive manufacturing processes based on non-ferrous metals.
 
Supported by the German government research program EffiLAS (Efficient high-power laser beam sources), the new laser series was developed by Laserline together with Osram and other project partners. The LDMblue diode lasers are obtainable in three standard configurations with 1,000, 500 or 300 W output power at beam qualities of 100 or 60 mm·mrad (LDMblue 1000-100 / 500-60 / 300-60). Thanks to the proven and compact LDM design for the 19‘‘ rack, the LDMblue lasers can easily be integrated in a space-saving manner into all common production lines. You can find detailed information about the Laserline LDMblue series online at www.laserline.com/ldm-blue.
 
Up till now, joining thin non-ferrous metal compounds using classic infrared lasers was only possible via a modified deep welding process with material reinforcements in the seam area. This was due to the strong reflexion in the infrared spectrum which required high energy inputs. However, light in the blue spectrum is absorbed by non-ferrous metals up to twenty times stronger than by infrared radiation. Thus, compared to conventional infrared lasers, less energy is naturally essential for fusing the workpiece surface. Even the thinnest copper components can be joined in this way without artificial material reinforcement.
