Recent developments in laser sources operating in the mid-IR (3–8 μ m) have been
motivated by the numerous possibilities for both fundamental and applied research. One …

Strong-field physics is currently experiencing a shift towards the use of mid-IR driving
wavelengths. This is because they permit conducting experiments unambiguously in the …

Since 2001 and the first demonstrations of the feasibility of generating and measuring
attosecond light pulses, attosecond science has developed into a very active and quickly …

Under ideal conditions, quantum metrology promises a precision gain over classical
techniques scaling quadratically with the number of probe particles. At the same time, no-go …

Atomic ionization by intense mid-infrared (mid-IR) pulses produces low-electron-energy
features that the strong-field approximation, which is expected to be valid in the tunneling …

Strong-field ionization and Rydberg-state excitation (RSE) near the continuum threshold
exhibit two phenomena that have attracted a lot of recent attention: the low-energy structure …

With the three-dimensional classical ensemble model, we revisited the recollision dynamics
in strong-field nonsequential double ionization (NSDI) by linearly polarized laser pulses …

Among the many methods to image molecular structure, laser-induced electron diffraction
(LIED) can image a single gas-phase molecule by locating all of a molecule's atoms in …

The ionization of atoms by strong, low-frequency fields can generally be described well by
assuming that the photoelectron is, after the ionization step, completely at the mercy of the …

We report on a first of its kind, to our knowledge broadband amplification in a Fe: CdSe
single crystal in the mid-IR beyond 5? µm. The experimentally measured gain properties …
