Laserline Diode Laser: A Paradigm Shift For more than twenty years, Laserline has been a major contributor to the continuous development of diode laser technology. The first lasers used in materials processing, such as gas and conventional solid state lasers, were large, stationary units of low efficiency. They were primarily used for the cutting and welding of metals. Just as the last century saw the move from the vacuum tube to the transistor, a similar transition is now taking place as the laser industry moves toward high power diode lasers or diode-based lasers. Turning electricity into light...

The output of Laserline lasers now extends into the multi-kilowatt range. At the same time, the company has been able to significantly improve the beam quality. Versatile solution for materials processing Thanks to their adaptability, diode lasers cover a wide range of applications in production processes. Today diode lasers are well established in many industrial sectors. They are primarily used for the welding of steel and aluminum, cladding, coating and repair welding as well as hard soldering and hardening. Diode lasers are also the preferred option for the welding of fiber composites or...

From Diode to Beam When it comes to industrial production, reliability and process efficiency are among the main requirements for machinery. Our products are designed for trouble-free continuous multi-shift operation, even under demanding operating conditions. Diode laser sources Intelligent stack management The laser source is made of multiple diode stacks consisting of individual diode bars. The laser power and the beam quality are mainly determined by the number of bars per stack and the total number of stacks in the source. Using smart, patented Laserline technology, the beams emitted by...

Modular design All diode lasers from Laserline are modular in design. This means that they are made of a few basic components: the laser source, the optical equipment, the supply unit and the control system with an optional control panel. Thanks to this modular design, diode lasers can be perfectly customized to suit the specific requirements of each customer while maintenance and spare parts costs are kept to a minimum. Connecting The diode laser can be easily integrated into external control systems using standard bus communication such as EtherNet/IP, analog and digital interfaces as well...

With fiber-coupled diode lasers from Laserline, the laser beam with a power of up to 50 kW is transferred to the workpiece through an optical fiber. Depending on the actual laser power, Laserline uses optical fibers of 100 μm to 2000 μm in diameter. Laserline provides industrial system solutions for laser machining. For efficient laser applications, the optics must be perfectly adjusted to the diode laser source. Laserline’s optic component range includes standard and specialized beam shaping optics as well as add-ons such as pyrometers and CMOS cameras for process monitoring and control. In...

Solutions for your Applications Brazing in body-in-white applications Diode lasers provide a particularly effective and compact heat source that can be adapted to a wide range of applications by means of add-on components and specialized optics. Welding of metals Diode lasers are widely used for sheet metal applications industrial series production. Joints produced with Laserline lasers are particularly strong and show only minimum deformation. Welds produced at high machining speeds achieve an excellent weld surface in heat conduction welding but also in deep penetration / key-hole welding....

Hardening / heat treatment Welding of tailored blanks Welding of tailored blanks A relatively recent application is the welding of tailored blanks with high power diode lasers. In this process, components made from different materials or different thicknesses are joined for subsequent forming, so that vehicle components can be optimized as regards their crash behaviour and weight. Brazing Brazing and welding with filler wire are well-established methods for joining metal components. As diode lasers are virtually maintenance-free, they are particularly suited to applications such as the brazing...
