title: Plasma-blueshift spectral shear interferometry for characterization of ultimately short optical pulses.
abstract: We introduce a bandwidth-unlimited, dispersion- and shear-self-calibrated, timing-jitter-free pulse measurement technique based on a quasi-linear temporal phase modulation in a gas weakly ionized by a long pump pulse. Results of a 5 fs pulse characterization are reported.
