Polarization gating of high harmonic generation in the water window

High harmonic spectrum from 50-350 eV is achieved via polarization gating technique using an OPCPA laser at 1.7 μm. The driving laser's carrier-envelope phase influence on the high harmonic generation yield indicates that isolated attosecond pulses are generated.
