Abstract
We show that it is possible to use CO2 laser radiation in an open atmosphere to dope high-temperature superconductors with oxygen. We show that, without using a vacuum chamber, high-temperature oxide superconductors can be doped to fabricate devices with electronics applications. The present experimental study shows that, for a given structure of high-temperature superconductor materials, irradiating the samples using an intense laser beam in an inert gas or an oxygen gas atmosphere can change the oxygen content. The reflection infrared spectra show that the laser irradiation of the samples has had suitable results on the samples. The x-ray diffraction spectra of the samples reveal that the intensities of some of the planes change dramatically.
