Abstract

A single beam of shaped femtosecond pulses is used to coherently control the Raman excitation and to simultaneously observe the resulting vibrations of molecules in a mixture resolved in time. This experimentally simple scheme opens up exciting new possibilities for the selective detection of dangerous chemical or bacterial species, such as spores, and will serve to enhance contrast in nonlinear Raman chemical imaging.
