Carlos Hernández García
Photonics and Laser Applications Group


I’m Carlos Hernández García and I am working as a Marie-Curie post-doctoral fellow at University of Salamanca (Spain).  I obtained my PhD in the University of Salamanca (January 2013), in the Research Group in Photonics and Laser Applications (ALF-USAL), under the supervision of Prof. Luis Plaja. The title of my PhD thesis was Coherent attosecond sources based on high-order harmonic generation: influence of the propagation effects. (Download PhD thesis in PDF). I did a two-year postdoc within the Marie Curie fellowship at JILA, University of Colorado at Boulder, in Becker’s group (also in collaboration with Kapteyn and Murnane’s group).

Fields of interest: Laser-matter Interaction, Ultrafast Phenomena, Nonlinear Optics, High-order Harmonic Generation and Propagation, Attosecond and Zeptosecond Physics,  and Orbital Angular Momentum, among others.
