Abstract :
Shirley´s analysis (1985) is generalized to calculate the fluorescence light shifts in various optically pumped Cs beam standards, especially in the two-beam type frequency standard that enables a real-time correction of an end-to-end cavity phase shift. Using tables of light shift coefficients and mean fluorescence photon numbers per atom, fluorescence light shifts in one- and two-beam type optically pumped Cs beam frequency standards using noncycling detection and cycling detection, are evaluated. Results obtained are useful to correct the fluorescence light shifts in optically pumped Cs beam frequency standards.<>
