Abstract

Near transform-limited 63-as high-harmonic pulses were successfully generated by compensating positive attosecond chirp of harmonics using negative group delay dispersion of Ar in broad spectral region. Without proper chirp compensation, the harmonic pulses were split into multiple peaks due to the large phase variation, in addition to the broadening of pulse duration. The chirpcompensated broadband harmonic pulses, approaching the transform-limited duration, will be very valuable for exploring ultrafast dynamics in atoms and molecules with high temporal resolution.
