Current frontiers of ultrafast and high field optics: Attosecond science

The development of novel tools for the generation of attosecond light pulses is continuously triggering the introduction of new spectroscopic and measurement methods, which will offer the opportunity to investigate unexplored research areas with unprecedented time resolution. In this work we will report on recent advances in attosecond science, with particular emphasis on the generation of isolated attosecond pulses produced by laser-driven high-order harmonic generation in gases. We will consider several approaches to attosecond metrology and we will present some applications of attosecond pulses. Future perspectives in attosecond technology will then be discussed.
