The embryonic development of femtoscience stems from advances made
in the generation of ultrashort laser pulses. Beginning with
mode-locking of glass lasers in the 1960s, the development of dye
lasers brought the pulse width down from picoseconds to
femtoseconds. The breakthrough in solid state laser pulse
generation provided the current reliable table-top laser systems
capable of average power of about 1 watt, and peak power density of
easily watts per square centimeter, with pulse widths in the range
of four to eight femtoseconds. Pulses with peak power density
reaching watts per square centimeter have been achieved in
laboratory settings and, more recently, pulses of sub-femtosecond
duration have been successfully generated. As concepts and
methodologies have evolved over the past two decades, the realm of
ultrafast science has become vast and exciting and has impacted
many areas of chemistry, biology and physics, and other fields such
as materials science, electrical engineering, and optical
communication. In molecular science the explosive growth of this
research is for fundamental reasons. In femtochemistry and
femtobiology chemical bonds form and break on the femtosecond time
scale, and on this scale of time we can freeze the transition
states at configurations never before seen. Even for n- reactive
physical changes one is observing the most elementary of molecular
processes. On a time scale shorter than the vibrational and
rotational periods the ensemble behaves coherently as a
single-molecule trajectory.
