1. (A and B) Fourier transform spectra obtained at different temperatures and excitation fluences in B1g (A, 1.91 eV probing energy) and A1g + B2g (B, 2.45 eV probing energy) geometries.
(A and B) Fourier transform spectra obtained at different temperatures and excitation fluences in B1g (A, 1.91 eV probing energy) and A1g + B2g (B, 2.45 eV probing energy) geometries. (C and D) Comparison between transient reflectivity data and Raman measurements, in the superconducting phase. The spontaneous Raman spectra are the difference between superconducting and normal phases, showing only the charge fluctuation peaks. Insets show schematically in C the angle ϕ along the Fermi surface and the regions in momentum space excited in B1g symmetry and in D the same for B2g symmetry.
