摘要：

We demonstrate fully phase-matched high harmonic emission spanning the water window spectral region important for nano-and bioimaging and a breadth of materials and molecular dynamics studies. We also generate the broadest bright coherent bandwidth (approximate to 300 eV) to date from any light source, small or large, that is consistent with a single subfemtosecond burst. The harmonic photon flux at 0.5 keV is 10(3) higher than demonstrated previously. This work extends bright, spatially coherent, attosecond pulses into the soft x-ray region for the first time.
