High-Harmonic Generation of Attosecond Pulses in the “Single-Cycle” Regime

Christov, Ivan P., Murnane, Margaret M., Kapteyn, Henry C.·1997·Physical Review Letters

Abstract

High-harmonic generation with excitation pulses shorter than 25 fs is studied theoretically using a 3D model. For very short excitation pulses, a new regime of harmonic generation by a ``single-cycle'' of the driver pulse can be reached. In this regime, the temporal coherence of the adjacent harmonic orders is dramatically improved compared with longer excitation pulses, even though the discrete harmonic structure in the emission disappears. X-ray pulses as short as 100 attoseconds can be emitted, with increased conversion efficiency of laser-to-harmonic radiation.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Isolated attosecond pulse generation is a special case where the emission is confined to a single peak in the laser field [121, 122], although all HHG emission occurs in attosecond bursts.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
