    Laserline - Diode Lasers for materials processing
    Laserline is working to increase the output power of the diode laser and improve the systems' reliability for industrial production. Our lasers reach high beam qualities up to 8 mm mrad at 4 kW output power. As the leading manufacturer of diode lasers for materials processing, Laserline and its products have become synonymous with this innovative technology. Diode lasers are used in production processes worldwide and prove efficient and reliable in a wide range of applications.

    Since 1999, the beam quality or maximum output from the same diameter fiber has doubled almost every two years, expanding Moore's law into the laser industry. Following this trend, Laserline is working to increase the output power of the diode laser and improve the systems' reliability for industrial production.

    At Laserline, we focus on the creative and disciplined transformation of new ideas into industrial innovations, and we adhere to the highest standards of quality. This enables us to develop customized system solutions that work economically and reliably, even under the toughest production conditions.

    LDF series (500 – 20,000 W)
    Fiber-coupled diode lasers in the LDF series offer output power from 500 W up to 20,000 W through optical fibers with 200 µm, 300 µm, 400 µm, 600 µm, 1,000 µm, 1,500 µm an 2,000 µm depending on the power level and the needs of the application.

    Fiber-coupled diode lasers
    In most cases, fiber-coupled diode laser heads are integrated into the compact and mobile supply unit in an all-in-one concept. In conjunction with stack and fault management, the supply unit guarantees maximum reliability in serial production. The laser system can be upgraded and adapted to different applications, for example, by adding diode laser stacks.

    Multiple Station Operation
    The diode lasers of the LDF series are particularly well suited to multiple station operation with beam switches and fibers of up to 100 m in length. The beam switch is integrated in the laser head and may also be added later, as customer requirements in production increase. It is equipped with an integrated status monitor and beam absorber.


    Diode lasers of LDF Series with beam converter
    With up to 4,000 W of laser power, the newly developed diode laser with integrated beam quality converter sets a new benchmark. Based on the long established and proven technology of actively cooled laser diodes, the beam parameter product has been optimized using an active fiber - the converter.

    Optimum Combination: High Power and Superior Beam Quality
    For the first time the usage of a beam converter opens up new applications which were previously unfeasible for diode lasers such as "Remote Welding", those which demands very small focus diameters, as well as "Laser Cutting". These applications expand the classic application portfolio of diode lasers, which includes sheet metal and aluminum welding, cladding, hardening and heat-treating.

    The principle of modularity is applied throughout. This makes it easy to adapt the beam source for specific applications. Applications with small focuses and corresponding power densities up to focal lengths of well over 500 mm can be implemented.

    Enhancement of LDF series
    The laser power is transferred to the workpiece by way of a robot-compatible fiber. The innovative improvement of diode laser beam quality based on an active fiber permits a choice of core diameter from 200 µm upward. This also provides for maximum reliability, easily delivering technical availability levels greater than 99 percent and even with multi-kW power outputs.

    The diode with 8 mm mrad is a technical enhancement of the existing highly successful LDF series based on laser diodes only. Starting from a standard diode laser, the laser beam at medium beam quality is first focused into an active fiber rather than a passive fiber. This improves the laser beam quality by conversion technology so that a beam quality better than 8 mm mrad is attained at the active fiber outlet. The wavelength of approximately 1085 nm is only slightly different from existing diode lasers. The downstream components such as the beam swith and passive fiber are also based on the existing and established components of the LDF series. The high degree of modularity of the diode laser enables the system to be upgraded subsequently for example by increasing the laser power or the number of beam outlets, or by adding other components.
