Interaction of a laser pulse with high-temperature-superconducting target Y-Ba-Cu-O

The interaction of a laser pulse with a high-temperature-superconducting target is studied on the basis of the heat conduction equation. It is found that the surface layer of the target overheats at certain radiation intensities. This overheating in turn disturbs the metastable state of the material and results in its explosive ejection from the surface.
