The Ultrafast Phenomena Conferences are held every two years and are widely recognized as the premier and main international forum for gathering the community of scientists and engineers working in research and technology related to ultrafast phenomena. It is indeed a unique opportunity to bring together atomic, molecular and condensed matter physicists, physical chemists, biophysicists and scientists developing new tools, methodologies and techniques, all working on the science of ultrafast phenomena. These phenomena cover the time scales ranging from picoseconds (1 ps = 10-12 s) to hundreds of attoseconds (1 as = 10-18 s).
