摘要: We generate high-order harmonics at high pulse repetition rates using a turnkey laser. High-order 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) 20 kHz. measure photon flux up to 4.4 × 1010 per second harmonic in 100 Many experiments employing would benefit from higher rates, and the user-friendly operation opens for applications coherent extreme ultra-violet pulses new research areas.
