We demonstrate a simple technique to significantly improve the long-term frequency stability in atomic clocks vased on coherent population trapping (CPT). In this technique an additional servo is used to control the local oscillator power level to ensure that the clock frequency is alwaus given to the atomic resonance frequency that is not perturbed by the incident light fields.
