Overview of application areasMany developments for precision machining, such as remote welding applications, require industrial-grade beam sources with high power and high brilliance. Here, the Laserline beam converter concept perfectly combines the modularity, practicality and cost effectiveness of LDF diode lasers with high beam qualities.
The beam converter is a technical enhancement of the proven LDF core technology with directly cooled laser diodes. Starting from a standard diode laser, a laser beam at medium beam quality is first focused into an active fiber – the converter. The converter module transforms the brilliance of the laser beam. In contrast to LDF systems without beam converter, the wavelength changes only slightly and is about 1080 nm. Different configurations thus enable an output power of up to 8 kW with brilliant beam quality of 4, 6 or 8 mm mrad.
With the latest Laserline LDF system design modularity, reliability and ease of maintenance are pursued consistently. Laser power, beam quality, the number of beam switches, cooling and auxiliary components can be configured individually and adapted to changing requirements. All system data are monitored and collected by the central control unit.
The operation and evaluation can be done with the mobile control panel directly on the laser, via network connection in a control center, as well as over secured remote access.
The laser energy is transmitted via pluggable and robot-suitable optical fiber. Depending on the beam quality, core diameters of 100 μm to 200 μm are available
1. Pump diodes
2. Active fiber
3. 2-exit beam switch
4. Passive fiber
