Energy scaling in a compact bulk multi-pass cell enabled by Laguerre-Gaussian single-vortex beams

Victor Koltalo, Saga Westerberg, Melvin Redon +5

We report pulse energy scaling enabled by the use of Laguerre-Gaussian single-vortex (${\text{LG}}_{0,l}$) beams for spectral broadening in a sub-40 cm long Herriott-type bulk multi-…
