Breakdown of the Dipole Approximation in Strong-Field Ionization
A. Ludwig, J. Maurer, B. W. Mayer +3
We report the breakdown of the electric dipole approximation in the long-wavelength limit in strong-field ionization with linearly polarized few-cycle mid-infrared laser pulses at…
Resonance effects in photoemission time delays
M. Sabbar, S. Heuser, R. Boge +6
We present measurements of single-photon ionization time delays between valence electrons of argon and neon using a coincidence detection technique that allows for the simultaneous…
Temporal and spectral disentanglement of laser-driven electron tunneling emission from a solid
Hirofumi Yanagisawa, Sascha Schnepp, Christian Hafner +4
By measuring energy spectra of the electron emission from a sharp tungsten tip induced by few-cycle laser pulses, the laser-field dependence of the emission mechanism was investiga…
Multiphoton transitions for delay-zero calibration in attosecond spectroscopy
Jens Herrmann, Matteo Lucchini, Shaohao Chen +7
The exact delay-zero calibration in an attosecond pump-probe experiment is important for the correct interpretation of experimental data. In attosecond transient absorption spectro…
Mid-infrared pulse generation via achromatic quasi-phase-matched OPCPA
Benedikt W. Mayer, Christopher R. Phillips, Lukas Gallmann +1
We demonstrate a new regime for mid-infrared optical parametric chirped pulse amplification (OPCPA) based on achromatic quasi-phase-matching. Our mid-infrared OPCPA system is based…
Energy-dependent photoemission delays from noble metal surfaces by attosecond interferometry
R. Locher, L. Castiglioni, M. Lucchini +5
How quanta of energy and charge are transported on both atomic spatial and ultrafast time scales is at the heart of modern technology. Recent progress in ultrafast spectroscopy has…
