Publikováno v: Physical Review X, Vol 14, Iss 1, p 011015 (2024)

Strong laser pulses enable probing molecules with their own electrons. The oscillating electric field tears electrons off a molecule, accelerates them, and drives them back toward their parent ion within a few femtoseconds. The electrons are then dif

1.9 mW XUV source by cascaded harmonic generation from an Yb:fiber laser

Autor: F. Guichard, Y. Zaouter, Yann Mairesse, Stéphane Petit, Dominique Descamps, Sandra Beauvarlet, A. I. Gonzalez, Antoine Comby

Publikováno v: OSA High-brightness Sources and Light-driven Interactions Congress 2020 (EUVXRAY, HILAS, MICS).

We demonstrate high XUV photon fluxes by producing high-order harmonics from a turnkey femtosecond Yb-doped amplifier. We thus show efficient XUV generation with 1.9 mW average power at 18 eV.

Publikováno v: Optics Letters. 46:1804

We present an efficient and robust scheme to produce energetic sub-15 fs pulses centered at 515 nm with a peak power exceeding 3 GW. Combining efficient second-harmonic generation of a 135 fs, 50 W Yb-doped fiber amplifier with a low-loss capillary-b
