High-order harmonic generation using a high-repetition-rate turnkey laser
High-order harmonic generation using a high-repetition-rate turnkey laser
We generate high-order harmonics at high pulse repetition rates using a turnkey laser. High-order harmonics at 400 kHz are observed when argon is used as target gas. In neon, we achieve generation of photons with energies exceeding 90 eV (∼13 nm) at 20 kHz. We measure a photon flux of …
