In ultra-short laser pulses,small changes in dispersion properties before the final focusing mirror can lead to severe pulse distortions around the focus and therefore to very different pulse properties at the point o...

Optical parametric chirped-pulse amplification is inevitably subject to high-order spatial chirp,particularly under the condition of saturated amplification and a Gaussian pump;this corresponds to an irreversible spat...
