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:研究了級聯三能級系統中的相位共軛極化拍頻光譜術.發現其對能級差的測量精度決定於光學躍遷的均勻增寬.在符合拍頻條件時，兩獨立光源拍頻的頻差可以超出激光線寬，激光絕對頻率的測量精度可達到與激光線寬同一量級
