Abstract :
We generated high-order harmonics with self-phase-stabilized near-IR pulses produced by a parametric source. We observed a significant cutoff extension whit respect to 800-nm driving pulses at comparable peak intensity. This result represents a step forward the generation of single attosecond pulses with photon energies exceeding 100 eV.
