Coherent Emission Light Source
Robert B. Griffiths, Robert Henry Dicke
Abstract
A sharp, intense emission line may be obtained by use of resonance radiation coherently scattered from a collimated beam of atoms. The coherently scattered light may be separated from the exciting radiation by placing the atomic beam in one arm of a Mach-Zehnder interferometer or by diffraction from several parallel atomic beam pencils. The latter technique has been tested experimentally by observing hyperfine structure in light coherently scattered from a beam of sodium atoms.
