Nanosecond and femtosecond laser ablation of pure and Y-doped BSCCO

This study investigates the effects of nanosecond and femtosecond laser ablation on pure and 30% Y-doped BSCCO oxide ceramics. The objective is to analyze the morphological and crystallographic characteristics of films produced by Pulsed Laser Deposition (PLD) technique. Employing scanning electron microscopy and X-ray diffraction, we reveal that the as-deposited films exhibit randomly oriented microspheres, while femtosecond ablation leads to the emergence of rod-like structures and nanoscaled spheres. Notably, XRD analysis confirms that femtosecond ablation can yield crystalline films without the need for additional heat treatment. The results underscore the advantages of femtosecond PLD in producing high-quality films with controlled morphology, compared to conventional nanosecond methods, which often result in detrimental micron-sized droplets. This research not only highlights the potential of femtosecond laser techniques in enhancing the deposition process but also expands the understanding of the physical properties of BSCCO films, paving the way for future applications in superconducting materials.
