Abstract

The extremely good focusability of thin disk lasers provides many advantages regarding the process as well as system aspects. Using commercially achievable devices up to 6 kW, considerable improvements in welding performance are demonstrated. At very small spot diameters, it was found that, in addition to the spot diameter itself, the divergence angle of the focussed beam is deciding for the seam shape.
