  4. Abstract : we have studied theoretically a beat effect in a four - level system due to fifth - order optical polarization, and considered the cases that the pump beams have either narrowband or broadband linewidth. we have found that the accuracy for the energy - level splitting measurement is determined by the homogeneous linewidths of the optical transitions. that is to say, this technique can achieve doppler - free precision in the measurement of the energy level splitting between two excited states which are dipolar forbidden from the ground state

    文摘:研究了四能級系統中基於五階極化的拍頻效應，考慮了抽運光束為窄帶線寬或寬帶線寬的情形.發現其對能級分裂的測量精度決定於光學躍遷的均勻增寬.也就是說，這種技術在測量與基態是偶極禁戒躍遷的兩激發態之間的能級分裂時，可得到消除多普勒增寬的精度
