TL;DR: In this paper, the Coulomb field was used to tune and probe the Coulomomb potential on the strong-field-driven wavepacket as observed by two-dimensional electron and ion momentum spectra.

TL;DR: In this paper, nonlinearity management versus energy scalability and compressibility in a three-stage monolithic 100-kHz repetition rate Yb-fiber amplifier designed as a driver source for the generation and tunable parametric amplification of a carrier-envelope phase stable white-light supercontinuum.

TL;DR: In this paper, the authors used the ''attoclock'' technique to control the two-electron emission dynamics on the time scale of a half laser cycle for sequential double ionization of helium.

TL;DR: In this article, Ramaman self-frequency shift in a photonic-crystal fiber with a core diameter less than 2 μm is used to transform the spectrum of a 6-fs 2-nJ Ti: sapphire-laser pulse, dominated by a 670-nm peak, into a spectrum featuring a well-resolved intense spectral component centered at 1064 nm, which is ideally suited as a seed for Nd: YAG-and ytterbium-based laser devices.

TL;DR: Properties of filaments ignited by multi-millijoule, 90 fs mid-infrared pulses centered at 3.9 μm are examined experimentally by monitoring plasma density, losses, spectral dynamics and beam profile evolution at different focusing strengths.
