Abstract

Ultrafast thin-disk lasers are based on the mature thin-disk technology. This technique allows for highest pump powers due to very efficient cooling. Therefore, the thin-disk geometry offers exceptional scaling of laser performance in terms of average power. Over the last decade industrial lasers for cutting and welding applications were continuously improved. More than 12kW can be obtained by a single thin-disk in continuous wave mode. TRUMPF Scientific Lasers uses the same thin-disk components to develop and manufacture ultrafast amplifiers. The achieved output power is close to 2kW with record pulse energies >95 mJ.
