Carrier-envelope-phase-independent field sampling of single-cycle transients using Homochromatic Attosecond Streaking

TL;DR

This paper demonstrates that Homochromatic Attosecond Streaking (HAS) can precisely sample the electric field of non-phase-stabilized, single-cycle light transients, enabling high-precision ultrafast metrology and waveform characterization.

Contribution

The study introduces a novel application of HAS for sampling single-cycle light transients independent of carrier-envelope phase stabilization.

Findings

HAS can isolate and track the waveform of a single CEP setting.

The method achieves attosecond-level precision in light field characterization.

HAS is shown to be a robust, compact, all-solid-state technique.

Abstract

The recent development of Homochromatic Attosecond Streaking (HAS) has enabled a novel, highly precise method for ultrafast metrology of attosecond electron pulses as well as for real-time sampling of the instantaneous field waveforms of light transients. Here, we evaluate the potential of HAS as a method for precisely sampling the field waveform of non-phase-stabilized, single-cycle transients of light. We show that the extreme nonlinearity of field emission allows our technique to isolate and track the waveform of a single carrier-envelope phase (CEP) setting whose field dynamics results in the most energetic electron cutoff. Our results establish HAS as a robust, compact, all-solid-state method for characterizing light fields with attosecond-level precision and as a powerful tool in light field synthesis.
