0.6 µm-wide lines of high Tc Y-Ba-Cu-O have been fabricated by direct laser writing on mirror-like thin films which were grown by laser deposition without post annealing. Laser ablation etching had no effect on the Tc and Jc until the lines were < 1µm wide. The 0.6 µm-wide strip showed some degradation of Tc and Jc. The critical current densities for these patterned lines were measured to be ∼5×106 A/cm2 at 50 K.
