Superconducting strips of 0.6 {mu}m width were fabricated by direct laser writing on mirror-like Y-Ba-Cu-O thin films on various substrates. These films were grown by laser deposition without post-annealing. Laser ablation etching had no effect on the {ital T}{sub {ital c}} and {ital J}{sub {ital c}} until the lines were {lt}1 {mu}m wide. The 0.6-{mu}m-wide strip showed some degradation of {ital T}{sub {ital c}}. The critical current densities for all patterned lines were measured to be {similar to}4{times}10{sup 6} A/cm{sup 2} at 20 {degree} K.
