Abstract
A 5-kW thin disk laser with a beam parameter product (BPP) of ≤ 2.5 mm×mrad (50-μm processing fiber) has been realized. Target applications of this device include high speed laser cutting and remote (wobble) welding. Furthermore, we present an 8-kW thin disk laser system with a BPP of 4 mm×mrad (100-μm processing fiber) based on one disk. We also present results on a 18-kW thin disk laser based on two disks (125-μm processing fiber). A new line of thin disk lasers with output powers of 1-6 kW is introduced: up to four fiber outputs allow for a wide variety of time and energy sharing schemes.
