The constant idea of renewable energy production plants is the low value of energy production, which prompted researchers to reduce energy loss in transportation and production. The major loss in electric systems is the heat loss gained by electric resistance of materials. There are too many research projects trying to reduce materials resistance, and the best method is using superconductor's materials. There are too many methods for enhancing the superconductor's electrical and structural properties by deferent approaches. This paper presents the influence of laser irradiation on the electric and structure properties of Y0.94Ag0.06Ba2Cu3O7−δ compound with different time irradiation (50, 100 and 150 second), which was investigated utilizing XRD analysis and four probes technique. The results of XRD showed that no phase transformations take place before and after laser irradiation, where the irradiated specimens have orthorhombic crystal structure too, but there are changes in peak intensities, lattice parameters, Mass density, oxygen content and volume fraction. Four probes technique was used to investigate the influence of irradiation on the critical temperature of prepared specimens. Test results explained that all specimens with different time irradiations exhibited changes exposed to laser ray, where it is noted that a specimen exhibits increase in its critical temperature by approximately 92 K, 97 K, 101 K and 107K.
