Attosecond science and technology have emerged as a promising path for improving our understanding of light–matter interaction. High harmonic generation based light sources combine high photon energy, broad spectrum, short duration with relatively compact implementation, which makes them flexible tools to study modify physical chemical properties matter by acting directly on electronic degrees freedom. Because extreme ultraviolet radiation interacts primarily outer inner valence electrons, it finds likely applications in atomic, molecular, material science. Despite their spectacular successes, the development these is still subject intense investigations, searching performances terms specifications reliability.

Frequency combs with mode spacing of 10–20 GHz are critical for increasingly important applications such as astronomical spectrograph calibration, high-speed dual-comb spectroscopy, and low-noise microwave generation. While electro-optic modulators microresonators can provide narrowband comb sources at this repetition rate, a significant remaining challenge is means to produce pulses sufficient peak power initiate nonlinear supercontinuum generation spanning hundreds terahertz (THz) required self-referencing.

Since its first demonstration in 2016, the multi-pass spectral broadening technique has covered impressive ranges of pulse energy (3 µJ - 100 mJ) and peak power (4 MW GW). Energy scaling this into joule-level is currently limited by phenomena such as optical damage, gas ionization spatio-spectral beam inhomogeneity. These limitations can be overcome novel convex-concave arrangement, which exhibits crucial properties large mode size compactness. In a proof-of-principle experiment, 260 fs, 15 200 pulses are broadened subsequently compressed to approximately 50 fs with 90% efficiency excellent homogeneity across profile. We simulate proposed concept for 40 mJ 1.3 ps input discuss possibility further scaling.
