LDF Series | Mobile High Power Diode Laser

Diode lasers for industrial applications in the multi-kilowatt range set the standard in terms of performance, mobility, efficiency and ease of maintenance

LDF Series: The Benchmark for High Power Diode Lasers

The LDF Platform - Thinking into the Future

With the LDF series Laserline is setting the benchmarks for high power diode lasers. Even devices with over 20kW 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.

A Modular Concept Allows Maximal Flexibility

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.

The New Benchmark for Power and Functionality

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.

The Intelligent System Control Makes a Difference

An industrial, latest-generation Ethernet network combines the different components and interfaces with the central control unit, which monitors the entire process in real time. An OPC-UA interface creates the prerequisites for a platform-independent, vertical and horizontal data communication. It enables the integration of lasers in modern concept architectures. All information is available at any time: on the mobile control panel directly on the laser or via network connection in a control center as well as over secured remote access.

Industrie 4.0 Communication with OPC UA

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.
