A dispersion-engineered multipass cell operating in the enhanced frequency regime is presented. Through the use of dispersive cavity mirrors, the nonlinear interaction is reshaped resulting in a smoother broadened spectrum, which yields a significant improvement in compressed pulse quality. The 70 W average power output of an Yb:fiber laser at 50 kHz repetition rate is compressed from 205 fs to 32 fs with more than 96% of the energy contained in the temporal main feature of the pulse.

- A multipass-cell system is used to compress 515 nm wavelength pulses from an Yb:fiber laser, reducing pulse duration from 240 fs to 15.7 fs.
- The system generates up to 0.44 mJ of energy and 22.4 W of average power at a frequency of 50.8 kHz, achieving over 40% overall efficiency.
- This technology enables efficient high-energy ultrashort pulses in the visible spectrum, paving the way for advanced high photon flux sources in future applications.
