Thin-disk multipass amplifier delivering sub-400 fs pulses with excellent beam quality at an average power of 1 kW

André Loescher, Florian Bienert, Christoph Röcker, Thomas Graf, Martin Gorjan, Jürg Aus der Au, and Marwan Abdou Ahmed

The paper reports on an improved multipass amplifier design, enabling the amplification of ultrashort pulses with excellent beam quality (M2<1.2) and average output power of more than 1 kW, corresponding to a peak power of 2.5 GW. Their amplifier system shows an excellent power stability of 0.16% RMS over a duration of more than two hours. The authors demonstrate the excellent performance of the laser technology by employing a simple multipass geometry with a strict attitude. The committee members unanimously selected this paper due to the exceptional thoroughness of the study, accuracy of the work, and clarity of the presentation. Read more.
