Abstract

We present the surface morphology of YBCO films deposited by laser ablation and optimization procedure of laser ablation to obtain epitaxial films with good surface quality. The optimization of the surface morphology of the films can be performed by carefully controlling the laser power to determine the growth rate and the homogeneity of films can be improved by rotating the ablating laser beam. These methods allow us to obtain high quality films with the transition width less than 1K, T_c of more than 90K and J_c more than 10⁶A/cm² at 77K. The optimized films were used to fabricate an 8-element high T_c superconducting microbridge with the size of 20 X 100 micrometers ². The optical response characteristics of the microbolometer array wee investigated in the region of 8-14 micrometers . The average noise equivalent power was 3.1 X 10^-12WHz^-1/2, the average normalized detectivity was 1.44 X 10⁹cmHz^1/2W^-1 and the nonuniformity of the average normalized detectivity was less than 10 percent.
