Long-term photoexcitation experiments were performed on YBa/sub 2/Cu/sub 3/O/sub x/ (x approximately=6.6) thin films, prepared by pulsed-laser deposition on "tilted" SrTiO/sub 3/ substrates. From the anisotropic resistance of the samples, the in-plane and the out-of-plane resistivities were calculated. Photoexcitation was carried out with a He-Ne laser at various temperatures from 70 K to 305 K. We observed that the electrical anisotropy rho /sub c// rho /sub ab/ increased at low temperatures, but decreased at high temperatures. This unusual behavior resembles that of the in-plane Hall mobility in a previous study. Possible interpretations according to the models for the photodoping effect in YBa/sub 2/Cu/sub 3/O/sub x/ are discussed.
