Abstract
We demonstrate sub-millijoule-energy, sub-4 fs-duration near-infrared laser pulses with a controlled waveform comprised of approximately 1.5 optical cycles within the full-width at half-maximum (FWHM) of their temporal intensity profile. We further demonstrate the utility of these pulses for producing high-order harmonic continua of unprecedented bandwidth at photon energies around 100 eV. Ultra-broadband coherent continua extending from 90 eV to more than 130 eV with smooth spectral intensity distributions that exhibit dramatic, never-before-observed sensitivity to the carrier-envelope offset (CEO) phase of the driver laser pulse were generated. These results suggest the feasibility of sub-100-attosecond XUV pulse generation for attosecond spectroscopy in the 100 eV range, and of a simple yet highly sensitive on-line CEO phase detector with sub-50-ms response time.
