Abstract : This patent concerns a laser excited molecular beam time and frequency standard utilizing a first electromagnetic beam at a first preselected frequency to excite a molecular beam at a first preselected point along the beam in order to produce fluorescence. A second electromagnetic beam (produced from either a different electromagnetic source than utilized to produce the first beam or produced from a portion of the first beam) at a second preselected frequency excites the molecular beam at a second preselected point along the beam to produce fluorescence. By locking the frequency of the first and second electromagnetic beams to specific resonant frequencies, a time and frequency standard can be produced.
