Kurzfassung:
We studied the optical response of Y 0.7 Pr 0.3 Ba 2 Cu 3 O 7-δ (YPBCO) thin films by means of a femtosecond time-resolved pump-probe method, and found that its response quite differs significantly from that of YBa 2 Cu 3 O 7-δ (YBCO) thin films. It is revealed that there are two components in the transient reflectivity change Δ R ( t )/ R of the YPBCO thin film in the superconducting state. The temperature dependence of Δ R ( t )/ R suggests that the one component originates from the photoexcitation of superconducting layers and the other originates from that of normal layers. The origin of these two components is discussed in relation to the electronic structure of YPBCO.
