LDF Diode Laser
Laserline LDF diode lasers set the standards for industrial applications in the multi-kilowatt laser range with regard to power, performance, mobility, efficiency and easy maintenance. They offer more power in less space than any other system in their class. LDF diode lasers are typically used for cladding, hardening, welding and brazing applications and are available with appropriate process heads and application specific accessories.

These lasers are mounted on sturdy castors allowing a single employee to move them to different locations for start-up in production – a unique benefit. All you need is electricity and water, the laser is then ready to use at its’ new site. Thanks to continuous development of the active diode cooling technology the LDF series family is optimised to multi-kilowatt levels at high beam qualities. For example, a power of 7kW out of a 600µm fiber at 0.1NA in a compact system configuration with a footprint of less than 1 square metre is possible!
With an electrical efficiency of up to 50% LDF diode lasers have the highest efficiency of all laser sources. The functionality leaves nothing to be desired; thanks to the hot-pluggable control panel these lasers can be monitored and controlled with flexibility, from a distance. In the unlikely event of a failure, the two stage fault management system identifies causes – and guides the user directly to efficient troubleshooting where appropriate. Service areas and interfaces are easily accessible, and system components can be easily replaced, avoiding any slowdown to the production process.
An industrial, latest generation Ethernet network combines the system components with the central control unit, which monitors the entire process in real time. All information is available at any time; directly on the laser, in a factory control centre via the network connection, as well as remotely over a secure connection. Most industrial automation bus based communications systems are also supported.
- flashlamp , the SWA is fiber-coupled and the SWT is YAG or fiber depending on the wavelength.">Laser Welding
- metallurgical bond High surface quality, hardly any post-processing is necessary The laser beam creates a molten pool at the workpiece surface, to which is simultaneously added the coating material wire or powder , also molten by the laser. The exposure time is short and creates only a short delay, as the cooling is quick. The result is a layer that is connected with the basic material metallurgically. It is tougher than the coatings created by thermal spraying, and compared to hard chromium plating for example, it is harmless to health. The favoured lasers for cladding applications are Laserline diode lasers, both the LDF and LDM series. The characteristics and the top-hat beam profile of the diode laser create a particularly even melt pool, which produces fine-grained, pore-free and crack-free coatings. Post-processing is therefore reduced to a minimum. They can also be used to create very thin coatings, which until now could only be realised by hard chromium plating. These lasers are readily integrated with robotic systems for automated processing, and offer a full 3D capability. We offer them complete with fiber-optic beam delivery, processing optics and powder or wire delivery nozzles. Special nozzles are available for cladding the internal surfaces of tubes.">Laser Cladding
- CW and Pulsed operation modes, which means fibre laser technology can be used for cutting, marking, cleaning, welding, additive manufacture and cladding with very low running costs. The fact that the beam can be created and delivered via a flexible fibre optic cable makes this technology easier to build and integrate - and less susceptible to knocks and bangs. Fibre lasers use a silica glass fibre that is doped with a gain medium such as Ytterbium or Thallium. These elements that are added / or doped in small quantities absorb photons of a low wavelength from a diode pump source , and then decay and emit a longer wavelength. It’s the creation of this longer wavelength that allows laser processing to take place. The fact that this all occurs within a fibre means that a high quality high power beam is created that remains tightly confined to a small spot size. This small spot size is well suited for performing cutting, marking and additive manufacture etc. where high energy concentrations are required. Defocusing the laser spot also allows it to be used for welding, cladding and other processes. Laser Lines can advise companies interested in this technology with trials to assess the suitability of this technology for a wide variety of applications.">Fibre
