Cleaning and surface treatment with pulsed high power fiber lasers

Surface treatment with high power pulsed fiber lasers gets more and more interesting to wide range of applications due to higher available average power and pulse energy. The average power is either increased by higher repetition rates or higher pulse energy. New laser concepts allow the parallel combining of several fiber laser modules up to an average power of several kilowatts. These lasers increase the efficiency of the processes by high removal rates. This paper gives an overview on the various applications of surface treatment such as cleaning of molds, depainting and surface preparation for welding and gluing.
