{ital In} {ital situ} growth of highly oriented YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} thin films (200--500 nm in thickness) has been obtained by pulsed KrF (248 nm) laser ablation on both rigid and flexible randomly oriented polycrystalline yttria-stabilized zirconia substrates. It is shown that {ital c}-axis-perpendicular YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} films with a mosaic spread of only 1.0{degree} can be grown on these randomly oriented polycrystalline substrates. Superconducting thin films were obtained with {ital T}{sub {ital c}}({ital R}=0){similar to}89 K on well-polished substrates. For the films deposited on the flexible substrates, the superconducting {ital T}{sub {ital c}} is not degraded by repeated bending of the flexible substrate/film composite over a 2.25-cm-radius arc although the normal-state resistivity increases slightly, suggesting the creation of microcracks. The YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} films grown on rigid polycrystalline yttria-stabilized zirconia substrates have a critical current density {ital J}{sub {ital c}}({ital H}=0){similar to}1400 A/cm{sup 2} at 77 K.
