Abstract

Since only a short time thin fiber cable, which can transmit high laser power, i.e. more than one kilowatt cw power, are on the market. To have a thin and at the same time powerful fiber has special advantages for material processing. It used to be a big problem to transfer laser radiation from the laser source over a long distance to the work piece. For material processing such as cutting or welding reproducable beam conditions at the focus point are necessary. By using mirrors for beam transportation, it is very normal that the stability at the focus point depends very much on the mechanical stability of the mirrors and on other factors influencing beam propagation. To avoid part of these problems sometimes the laser head was mounted on 1 or 2 axis of xy table, see fig. 1. A lot of work has been invested in the past years to optimize mirror systems for CO₂ lasers, when sheet metal of larce format bad to be cut.
