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 () beams for spectral broadening in a sub-40 cm long Herriott-type bulk multi-…

Sub-cycle Nanotip Field Emission of Electrons Driven by Air Plasma Generated THz Pulses
Benjamin Colmey, Rodrigo T. Paulino, Gaspard Beaufort +1
Terahertz pulses generated by two-color laser plasmas have reported peak field strengths exceeding MV/cm, and when illuminating metal nanotips the near-field enhancement at the tip…
