ABSTRACT:
There is disclosed a device for forming a thin film on a substrate by irradiating a target of a compound oxide superconducting material with a laser beam and evaporating on the substrate a thin film corresponding to a composition of the target in an oxygen ambient atmosphere by laser evaporation, a scanning optical system for causing the laser beam to scan being disposed in an optical path of the laser beam.
