Abstract : we have studied the polarization beats spectroscopy with phase - conjugation geometry in a cascade three - level system. it was found that the accuracy for the energy - level difference measurement is determined by the homogeneous linewidths of the optical transitions. under 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
