Abstract:

A laser stimulated Raman molecular beam time and frequency standard utilizes a first electromagnetic beam at a first preselected frequency to pump a molecular beam at a first preselected point along the beam to state select the beam. 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 and a third electromagnetic beam at the first frequency simultaneously pump the molecules of the state selected molecular beam at a second point along the beam in a stimulated Raman process. By locking the frequency difference of the first and second electromagnetic beams to a specific resonant frequency, a time and frequency standard can be produced.
