Abstract
We investigate a recently proposed scheme for differential detection of the magneto-optical rotation effect and its application to electromagnetically induced transparency (EIT) atomic clocks. This scheme utilizes a linearly polarized bichromatic laser field that is EIT-resonant with alkali atoms. The results of our study reveal that the suppression of the laser noise can substantially improve the signal-to-noise ratio in EIT atomic clocks. Our preliminary results demonstrate an order of magnitude improvement in clock stability under some conditions when incorporating the differential detection scheme
