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.
