Coherence control of high-order harmonics
WebThe reduction in the dot size below the classical electron oscillatory radius and the corresponding scattering limits the maximum acceleration by the laser field. Moreover, this scattering leads to a chaotization of motion, causing dephasing and a loss of coherence, therefore suppressing the efficiency of the emission of highest-order harmonics.

WebThe coherence-derived coherence factor (CF) [ 27] estimates the ratio of coherent energy to incoherent energy and directly weights the DAS beamformed data to reduce sidelobes. It can reduce the effects of phase aberration and reverberation and thus reduce artifacts from weakly coherent off-axis scatter and the granting lobe. WebHigh harmonic generation (HHG) is a non-linear process during which a target (gas, plasma, solid or liquid sample) is illuminated by an intense laser pulse. Under such …
