Yb-based lasers are characterised by their ability to operate at high average power and high repetition rates. However, they are limited by relatively long Fourier transform limit pulse duration, typically spanning from 100 fs up to the few ps regime. To overcome these challenges, multi-pass cells (MPCs) are becoming an increasingly attractive solution. They allow operation at high peak and average power while maintaining high efficiencies (>90%), high compression ratios, compact setup sizes and excellent beam quality. [1][L. Silletti et al.Optics Letters, 48(7), 1842-1845]. Here we present tunable 3fs transform-limited deep-UV light generation by driving resonant dispersive waves (RDWs) in an argon-filled hollow core fibres [2][J.C. Travers et.Nat. Photonics 13, 547-554 (2019)] cascaded by a single-stage dispersion-engineered MPC, which is capable of compressing 150-fs pulses to sub-20-fs durations with scalability from 1kHz up to 200kHz.
