Abstract

Coherent transient spectroscopy of atoms, molecules and defects in solids have provided considerable information about various dynamical processes in these systems. For semiconductors, many scattering processes occur on picosecond and femtosecond timescales. With the availability of ultrafast lasers with pulses as short as 6 fs, investigation of the properties of coherent states excited in semiconductors, and the scattering processes that destroy this coherence, has become an exciting new area of research. Such investigations have led to new insights into dynamical processes of fundamental interest in semiconductor physics.
