Félix Quintero Martínez is member of the LaserON Research Group on Laser Applications, where he is mainly involved in Laser Materials Processing from macro-processes such as cutting and surface treatment to nano-scale processes. He, together with other colleagues from the Research Group on Laser Applications, Applied Physics Dept. of University of Vigo, is co-inventor of the Cofiblas technique, a novel method developed to produce continuous glass nanofibers by laser melting, and, also among others, the Laser Spinning technique aimed to produce mats of glass nanofibers. His current research activity is focused on the laser processing of ceramics and glasses, especially in the application of the Cofiblas technique to produce glass nanofibers with outstanding mechanical properties and their applications.
