Ultrafast science is a highly multidisciplinary field covering the study of ultrafast phenomena in physics, chemistry, biophysics and engineering, optical communication, ultrafast electronics, medicine, and materials science. Recently, it was demonstrated that these pulses could be amplified to phenomenal peak powers, i.e. terawatt, petawatt - enough to drive the electron relativistically during one period of the laser field. These ultraintense pulses make possible the generation of ultrashort pulses in the extreme-ultraviolet regime, opening a new spectral window for the time-resolved science. Ultrafast Phenomena IX is the proceedings of the Dana Point Meeting and summarizes the state of the art as of May 1994.
