Spectroscopic Manifestations of Coherence Effects in the Laser-Molecule Interaction

Recent advances in quantum optics have led to the discovery of many novel and remarkable phenomena such as electromagnetically induced transparency (EIT), lasing without inversion, spontaneous emission cancellation etc. The underlying effect in all of these cases is the destructive interference between different excitation pathways leading to the reduction or full cancellation of the transition probabilities.

The general system under consideration of the majority of earlier works has been a three level atomic configuration, a closed system driven by one or two laser fields. We describe here our work on EIT and Autler-Townes splitting in open molecular systems with applications to molecular angular momentum alignment and enhancement of access to dark triplet states through laser control of quantum state character.
