We observe photoelectron spectra from above-threshold ionization of xenon using carrier-envelope phase-stabilized few-cycle pulses at 1.6 mu m. The signature of elastic scattering is imprinted on the spectra, and through careful analysis we succes...

A high-flux, soft x-ray light source, based on high harmonic generation, using 1.5-mJ, 10.1-fs IR pulses with CEP stabilization, has been constructed and used to resolve the 1s-pi* and - sigma* transitions in absorption spectra at the carbon K edge.

We generate a 75-eV-wide continuum in the water window via the HHG process using CEP-stabilized, few-cycle IR pulses. A pressure dependence of harmonic spectra indicates sub-cycle deformation of the IR pulses in the process.

We present long-term stability of the carrier-envelope phase of intense infrared few-cycle pulses at 1.6 mu m, generated by optical parametric chirped-pulse amplification. The employed system is based on a passive stabilization scheme that obviate...
