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
文摘:研究了级联三能级系统中的相位共轭极化拍频光谱术.发现其对能级差的测量精度决定于光学跃迁的均匀增宽.在符合拍频条件时，两独立光源拍频的频差可以超出激光线宽，激光绝对频率的测量精度可达到与激光线宽同一量级
