Wang, Y. Lee, Y.-J. Chen, W. Tang, C. Luo, A. Yabushita, K. Wu, J.-Y. Lin, J. Juang, T. Uen, T. Kobayashi] The quasiparticle relaxation dynamics in optimally doped (001) YBa2Cu3O7−δ thin films were measured at various temperatures by white light pump-probe technique. The 2D ultrafast spectroscopy with broadband (∼200nm) and high time-resolution (∼9 fs) was performed by the non-collinear optical parametric amplifier (NOPA). The relaxation time and the amplitude of the transient transmissivity changes (ΔT/T) are wavelength-dependent. The maximum ΔT/T appears at around 625 nm (∼1.98 eV) which corresponds to the transition between the Fermi level and the UHB (upper Hubbard band). Furthermore, the oscillations with ∼150, ∼320, ∼500 cm−1 have been clearly observed in the Fourier transformed graph of the 2D ultrafast spectroscopy, which are consistent with the phonon modes in Raman-scattering spectra.
