摘要：
The results of laser annealing of bulk high-temperature superconductors YBa2Cu3O7-x and Bi2Sr2Ca2Cu3Oy are reported. It is shown that nanosecond pulsed laser treatment of superconductors without further high-temperature processing leads to increasing of critical current density of surface layers of the samples up to 3-4 order within certain interval of laser energy densities due to melting and following crystallization of thin surface layers without degradation of superconducting phase.
