      abstract     = {The serrodyne principle enables an electromagnetic signal
                      to be frequency shifted by applying a linear phase ramp in
                      the time domain. This phenomenon has been exploited to
                      frequency shift signals in the radiofrequency, microwave and
                      optical regions of the electromagnetic spectrum over ranges
                      of up to a few gigahertz, for example, to analyse the
                      Doppler shift of radiofrequency signals for noise
                      suppression and frequency stabilization. Here we employ this
                      principle to shift the centre frequency of high-power
                      femtosecond laser pulses over a range of several terahertz
                      with the help of a nonlinear multi-pass cell. We demonstrate
                      our method experimentally by shifting the central wavelength
                      of a state-of-the-art 75 W frequency comb laser from
                      1,030 nm to 1,060 nm and to 1,000 nm. Furthermore, we
                      experimentally show that this wavelength-shifting technique
                      supports coherence characteristics at the few hertz-level
                      while improving the temporal pulse quality. The technique is
                      generally applicable to wide parameter ranges and different
                      laser systems, enabling efficient wavelength conversion of
                      high-power lasers to spectral regions beyond the gain
                      bandwidth of available laser platforms.},
