Superconducting Bi{sub 2}Sr{sub 2}Ca{sub {ital n}{minus}1}Cu{sub {ital n}}O{sub {ital x}} ({ital n}=1,2,3) films, with the {ital c}-axis perpendicular to the films, were fabricated by laser deposition. Oxygen pressure was found to be important to control the phases, and a unique pressure dependence of Bi-Sr-Ca-Cu-O phases was shown by these films. {ital T}{sub {ital c}} of 76 K and {ital J}{sub {ital c}} of 1.5{times}10{sup 5} A/cm{sup 2} at 40 K were achieved for the {ital in} {ital situ} Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub {ital x}} film. The critical-current densities in the external magnetic field up to 5 T with the fields parallel and perpendicular to the {ital c}-axis of the film were measured.
