摘要

We report an optical study of the superconducting transition in the YBa sub(2)Cu sub(3)O sub(7-x) films on MgO substrate carried out by femtosecond pump-probe spectroscopy. In both the normal and the superconducting state, we have observed the transient time-resolved reflectivity caused by the oscillations associated with two A sub(1g) metal-ion modes. Temporal interference between the modes is modified below the phase transition, which also appeared in an altered relative intensity of the modes in the Fourier transformed spectra.
