  • One of the major factors which effect the accuracy of optically pumped cesium frequency standards is caused by microwave leakages. Fourier transform is the major method to analyze the frequency offsets of small optically pumped cesium frequency standards, which is limited to analyze the case of atomic velocity being in narrow distribution. Formula of the frequency shift as a function of microwave leakages are derived by analysis and calculation. The results of calculation and analysis indicate that the magnitude of frequency offset caused by leaking microwave fields is in dependence on the length of the free field region,microwave power and the phase,amplitude and the position of the leaking microwave fields. The derived results are consistent with the conclusion which was educed by using the method of Fourier transform. However, the method is not limited by the velocity distribution of atom.
