Abstract :
We report the results of mathematical modeling the frequency stability for three types of rubidium gas cell frequency standards : with continuous and pulse laser pumping and with coherent population trapping (CPT). A critical point for using laser pumping in RFS which defines essentially the frequency stability is the influence of laser emission´s frequency fluctuations. The effect of these fluctuations on frequency stability of RFS variants´ considered is analyzed. Based on studies performed, the achievable stability for these RFS variants are compared.
