Scientific applications often require higher average output powers, even with high pulse energies. Based on the extensive experience with highest average power continuous wave laser systems by TRUMPF a more powerful regenerative amplifier system is currently under development by TRUMPF Scientific Lasers. This laser uses two disk laser heads inside the same cavity to provide more than 1kW average output power. First results show an average power of more than 1kW at repetition rates of 10kHz and higher. A pulse duration below 1ps could be reached.
