Abstract

We demonstrate a technique for frequency measurements of atomic transitions with a precision of 30kHz. The frequency is measured with a ring-cavity resonator whose length is calibrated against a reference laser locked to the $D_2$ line of $^{87}Rb$, the frequency of which is known with 10-kHz accuracy. We have used this method to measure the hyperfine structure in the $5P_{3/2}$ state of $^{87}Rb$. We obtain precise values for the hyperfine constants, A=25.04(16) MHz and B=26.013(25) MHz , and a value of 77.992(20)MHz for the isotope shift in the $D_2$ line.
