Physical Review A
An optical heterodyne technique based on the coherent Raman effect is demonstrated for detecting nuclear magnetic resonances (NMR) and coherent spin transients in normal and optically excited impurity-ion solids at low temperature. Initial measurements on Pr3+: LaF3 provide the first spin-echo studies of an electronically excited state, and cw resonances yield NMR line centers and shapes with kilohertz precision. © 1983 The American Physical Society.
