We perform an alternative approach to produce highly unipolar terahertz pulses. The idea is
based on the nonuniform amplification of seed ultrashort carrier-envelope phase (CEP) …

Extreme-ultravoilet (XUV) attosecond pulses with durations of a few tens of attosecond have
been successfully applied for exploring ultrafast electron dynamics at the atomic scale. But …

Abstract Sub-10 attosecond pulses (APs) with half-cycle electric fields provide exceptional
options to detect and manipulate electrons in the atomic timescale. However, the availability …

We propose a strikingly simple method to form approximately unipolar half-cycle optical
pulses via reflection of a single-cycle optical pulse from a thin flat metallic or dielectric layer …

Recent progress in generation of optical pulses of durations comparable to one optical cycle
has presented great opportunities for studies of the fundamental processes in matter as well …

Giant half-cycle attosecond pulse generation in the coherent bremsstrahlung emission
regime is proposed for laser pulses with normal incidence on a double-foil target, where the …

We propose a new method for producing terahertz (THz) pulses with a high degree of
unipolarity. This idea is based on the nonuniform amplification of seed THz one-cycle carrier …

Relativistic flying mirrors in plasmas are realized as thin dense electron (or electron–ion)
layers accelerated by high-intensity electromagnetic waves to velocities close to the speed …

Ultrafast extreme ultraviolet (XUV) sources with a controllable polarization state are powerful
tools for investigating the structural and electronic as well as the magnetic properties of …

Novel phase-locked acceleration of a relativistic isolated attosecond electron sheet was
realized using a relativistic reflected spatiotemporal optical vortex (STOV) pulse in three …
