Research on the Influence of Laser Radiation Parameters and Conditions in the Deposition Chamber on the Laser Ablation of YBCO Ceramics
摘要
Abstract
The paper presents the results of a study on the efficiency of laser ablation of superconducting YBCO ceramics, determined by the mass evaporated per pulse. It was found that the sizes of particles ejected from the target significantly depend on the pulse repetition rate and the target temperature, with their reduction contributing to a decreased likelihood of melt formation in the target crater and a reduction in the quantity and size of large particles on the superconducting YBCO film.
