DIODE LASER SYSTEMS - DIRECT BEAM & FIBRE DELIVERY Diode laser systems more and more play an important role in industrial material processing for applications like plastic welding and soldering. Their major advantages are easy integration into fully automated production units, touchless heating of the work piece, easy access even in case of complex geometries, precise energy deposition, excellent controllability and stability of laser power and high electrical/optical effciency at reasonable costs.
