Free-electron lasers and high-harmonic-generation table-top systems are new sources of
extreme-ultraviolet to hard X-ray photons, providing ultrashort pulses that are intense …

Recently two emerging areas of research, attosecond and nanoscale physics, have started
to come together. Attosecond physics deals with phenomena occurring when ultrashort laser …

Real-time observation of ultrafast dynamics in the microcosm is a fundamental approach for
understanding the internal evolution of physical, chemical and biological systems. Tools for …

The possibility of suddenly ionized molecules undergoing extremely fast electron hole (or
hole) dynamics prior to significant structural change was first recognized more than 20 years …

Sources of short wavelength radiation with femtosecond to attosecond pulse durations, such
as synchrotrons or free electron lasers, have already made possible numerous, and will …

The long-standing scientific quest of real-time tracing electronic motion and dynamics in all
states of matter has been remarkably benefited by the development of intense laser-based …

I review the historical observation and subsequent research on optical soliton dynamics in
gas-filled hollow-core optical fibres. I include both large-core hollow capillary fibres, and …

Attochemistry aims to exploit the properties of coherent electronic wavepackets excited via
attosecond pulses to control the formation of photoproducts. Such molecular processes can …

Carrier–envelope phase stable 4 fs near-IR pulses with 3 mJ energy were generated by
spectral broadening of circularly polarized 8 mJ pulses in a differentially pumped 2 m long …

In view of the rapid growth in both experimental and theoretical studies of multiphoton
processes and multiphoton spectroscopy of atoms, ions and molecules in chemistry …
