With the LDF series Laserline is setting the benchmarks for high power diode lasers. Even devices with over 30 kW laser power are set on sturdy castors allowing a single employee to move the laser to different locations for start-up in production – a unique benefit. All you need is electricity, water and an optical fiber – and the laser is ready for use at its new site.
Thanks to permanent development of our proven active diode cooling technology the LDF series family is optimized to multi-kilowatt power levels even at high beam qualities: 8 kW out of a 600 µm fiber at NA 0.1 in a compact configuration at less than one square meter footprint.
Be it power, cooling or system interfaces: The LDF series can be individually configured and adapted to changing requirements. The lasers are available with internal or external cooling system as a water/water or water/air variant.
With these Laserline chillers, perfectly aligned to the product line and fully integrated in the control cycle, high power lasers can now be operated permanently in production with a low footprint requirement. Through the internal networking of all components malfunctions can be diagnosed in real-time and resolved immediately.
LDF diode lasers are highly economical: with an efficiency of over 50 percent, they have the highest technical efficiency of all laser types. And the functionality leaves nothing to be desired: Thanks to the mobile hot-pluggable operating unit, the LDF lasers can be monitored and controlled very flexibly, even from a distance.
The three-stage troubleshooting management system displays information, warning and error messages, identifies causes and, if necessary, guides you directly to efficient troubleshooting.
Connection areas and interfaces are easily accessible thanks to a pull-out cover. System components can be easily replaced - so production does not come to a standstill.
An OPC UA interface creates the prerequisites for platform-independent, vertical and horizontal data communication. It enables the integration of lasers, fibers and processing optics in modern system architectures and forms the basis for new digital laser solutions.

Designed with a single high-power diode beam source, this system features two standard beam exits, enabling users to switch between fiber outputs depending on the specific task – without the need for multiple laser systems. Depending on the maximum output power of the installed laser, the 1,000 μm standard process fiber can deliver output powers exceeding 20 kW. This empowers hybrid configurations for a broad variety of use cases involving cladding, heat treatment, or other surface treatment processes as well. The 50 μm or 75 μm Active Process Fiber APF provides output powers of up to 6 kW tailored for welding, cutting, or other fine-material applications.
Thanks to their high modularity and flexibility, our LDF mobile high power diode lasers are suitable for a wide range of applications. A selection of the most common applications with diode lasers can be found here.
