We have achieved ablation of Bi-Sr-Ca-Cu oxide from single targets of superconducting pellets by CO{sub 2}-laser pulses of l ms length to grow superconducting thin films. Upon annealing, the 6000-A thin films have a {ital T}{sub {ital c}} (onset) of 90 K and zero resistance at 78 K. X-ray diffraction patterns indicate the growth of single-phase thin films. This technique allows growth of uniform single-phase superconducting thin films of lateral area greater than 1 cm{sup 2}.
