    How to optimize high-order harmonic generation in gases

    High-order harmonic generation (HHG) in gases leads to short-pulse extreme ultraviolet (XUV) radiation that is useful in a number of applications, such as attosecond science and nanoscale imaging. However, thi...

    Space–time control of free induction decay in the extreme ultraviolet

    Ultrafast extreme-ultraviolet (XUV) and X-ray sources are revolutionizing our ability to follow femtosecond processes with ångström-scale resolution. The next frontier is to simultaneously control the directio...

    High-Order Harmonic Generation and Plasmonics

    Attosecond pulses allow for imaging of very fast processes, like electron dynamics. Stockman et al. suggested to use these pulses in connection with a Photoemission electron microscope (PEEM) to study the ultr...

    Streak formation as side effect of optical breakdown during processing the bulk of transparent Kerr media with ultra-short laser pulses

    Femtosecond lasers have been successfully used to perform refractive surgery, by cutting within the bulk of the corneal tissue. As a side effect to the laser cutting there, a streak-like discoloration is obser...
