Abstract
We study the optical response of Y0.7Pr0.3Ba2Cu3O7-delta (YPBCO) films by m eans of a reflection pump-probe method and a photoexcited terahertz (THz) r adiation measurement with femtosecond (fs) optical pulses. It is suggested that photoexcited quasiparticle dynamics of YPBCO is not affected by Pr dop ing though the magnitude or polarity of the optical reflection response is dependent on the photon energy.
