A Single-Stage Dispersion-Controlled Multi-Pass Cell Setup to Efficiently Drive Resonant Dispersive Wave Emission

As Yb-based ultrafast laser systems are gaining importance due to their high average power compatibility while operating at high repetition rates, spectral broadening techniques are employed to overcome their limit in pulse duration. For this purpose, multi-pass cells (MPCs) have emerged as an attractive solution providing high efficiency, large compression ratios, compact setup sizes and excellent beam quality [1]. However, compression to the few-cycle regime has only been achieved in cascaded arrangements of MPCs [2].
