Coherent optical transients

MAY 01, 1977

A new branch of optical spectroscopy that deals with the optical analogs of spin transients such as NMR is providing unique ways to explore dynamic interactions in optically excited atoms, molecules and solids.

The dynamics of nuclear spins in atomic and molecular environments have been examined in exquisite detail over the past 27 years by the methods of pulsed nuclear magnetic resonance. The early discovery of the spin echo by Erwin Hahn and the transient nutation effect by Henry Torrey initiated the field by introducing coherent transient phenomena to radio-frequency spectroscopy. An entire class of coherent spin transients could be observed by a simple variation of the rf pulse sequence, and from the decay characteristics the various spin‐dephasing mechanisms could be examined separately. In short, these methods allowed decomposition of the spin‐transition linewidth into its broadening components, and also offered new and versatile ways for performing high‐resolution rf spectroscopy.
