摘要: We present a tabletop source of coherent soft x-ray radiation with high-photon flux. Two-cycle pulses delivered by fiber-laser-pumped optical parametric chirped-pulse amplifier operating at 180 kHz repetition rate are upconverted via high harmonic generation in neon to photon energies beyond 200 eV. A maximum flux 1.3·108 photons/s is achieved within 1% bandwidth 125 eV energy. This corresponds conversion efficiency ∼10−9, which can be reached due gas jet simultaneously providing target density and phase matching. Further scaling potential toward higher as well discussed.
