Extended Data Fig. 10: Reconstruction of the harmonic fields from the measured FEOS signals.
From: Extremely efficient terahertz high-harmonic generation in graphene by hot Dirac fermions
This is an example of THG measurement with f = 0.68 THz → 3f = 2.04 THz. a, Measured FEOS signals (dimensionless). b, The corresponding fields transmitted through the incidence interface of the sample after deconvoluting the response functions of all the elements after the graphene film, including the 1.9-mm-thick ZnTe detection crystal, the 1.93-THz filter and the fused silica substrate from the FEOS signals in a. Black pulse is for the bare substrate, red for the graphene sample and blue for the difference. c, The pure THG field extracted from the blue field pulse in b.
