  1. 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
  2. The main works and results we have accomplished are as follows : 1 ) red - detuned locking of cooling / trapping laser to the cycling transition of cesium cooling has been accomplished by means of a double - passed acoustic - optical frequency shifting system and the technique of saturated absorption spectroscopy. the short - term residual frequency jitter is less than 350khz ; 2 ) automatic controlling system by computer programs has been established for laser cooling and trapping and cavity qed experiment. the laser and magnetic fields can be controlled by the acoustic - optical modulator and the electronic - controlled logic gate respectively

    具體如下： 1 ）採用了往返兩次通過的聲光頻移系統結合飽和吸收光譜技術的實驗方案，實現了冷卻俘獲激光頻率相對于銫原子冷卻循環躍遷的負失諧鎖定，短期頻率穩定度約在350khz以內，並可方便地調節其負失諧量而無須對后續光路再作調整； 2 ）建立了一套基於計算機程序控制的、銫原子激光冷卻與俘獲實驗所需的時序控制系統。
  3. With time - evolution - operator, it is proved that the population of upper level is in circumstance of cyclic oscillation by laser pulses pair of gaussian line - shape in a homogeneous broadening two - level system. the oscillatory time oxide is the delay time between the laser pulse pairs and the oscillatory frequency equals the one of transition between the lower and upper level

    引入時間演化算符，證明均勻增寬二能級體系在飛秒激光脈沖對作用下上能級激發態布居是周期性變化的，它以飛秒脈沖對之間的延時為時間軸，以該原子能級之間的躍遷頻率為振蕩頻率
  4. We also show the relationships between the frequency of the external laser fields and the transition of the qubit in the two - qubit conditional geometric quantum phase - shift gate, explaining in detail how the transition of the qubit depends on the the external laser fields and the states of the controlling qubit. we also detail the theoretical ideas which explain how to control effectivly the two - qubit conditional geometric quantum phase - shift gates through external laser fields

    我們得到了外加激光場頻率跟兩量子位條件幾何量子相移門中的量子位躍遷之間的關系，詳細地說明了量子位的躍遷是怎樣依賴于外加激光場和控制量子位的狀態的，從理論上解釋了如何利用外加激光場有效的控制兩量子位條件幾何量子相移門。
