In a general overview of findings he and fellow researchers have obtained over the past few decades, Letokhov (laser spectroscopy, Russian Academy of Sciences) describes the fundamentals of the laser selection of atomic and molecular velocities for Doppler-free spectroscopy, the laser trapping and cooling of atoms, and laser control of atomic and molecular ionization and dissociation in order to detect single atoms and molecules and separate isotopes and nuclear isomers.
