| Abstract: | The polarization beats in a cascade three-level system have been studied. We have found that the accuracy for the energy-level difference measurement is determined by thd homogeneous linewidths of the optical transition. In the condition for the occurrence of beating, the frequency difference of the beat between two independent light sources could exceed the laser linewidth. The measurement accuracy for laser absolute frequency could reach the same order of magnitude as the laser linewidth. |
| Keywords: | polarization beats energy-level difference laser absolute frequency |
