in the 1990s enabled transformative advances in intense laser–matter interaction physics …

Attosecond metrology has so far largely remained limited to titanium: sapphire lasers
combined with an active stabilization of the carrier-envelope phase (CEP). These sources …

The motion of electrons in the microcosm occurs on a time scale set by the atomic unit of
time—24 attoseconds. Attosecond pulses at photon energies corresponding to the …

As a compact and burgeoning alternative to synchrotron radiation and free-electron lasers,
high harmonic generation (HHG) has proven its superiority in static and time-resolved …

Fully coherent, soft X-ray attosecond pulses are now available through high-order harmonic
generation (HHG); however, the output energy is insufficient for various applications, such …

The generation of power-and wavelength-scalable few optical cycle pulses remains one of
the major challenges in modern laser physics. Over the past decade, the development of …
