Laser control of physicochemical processes; experiments and applications

This review outlines experimental advances that have been made in laser control of physicochemical processes, with an emphasis on the 2004–2006 period. After a brief introduction, an overview of the technology available for delivering ultrashort shaped femtosecond pulses is presented. Special attention is given to recent progress on laser control of chemical reactions and the application of this concept to molecular identification. We also cover control of simpler systems such as atoms and diatomic molecules. Laser control of large molecules in solution is also reviewed from the point of view of selective spectroscopic excitation with applications in microscopy and control of nanoparticles. We conclude with an outlook that takes into account the physical limitations that will dictate the best strategies to achieve robust laser control of physicochemical processes.
