  1. We analyze the influences of the perturbed energy - level space and superposion, laser power and intermediate level offset on quantum interference. experimentally, in the sodium dimmer rhomb - type four - level system with a pair of perturbed levels, the interference enhancement of two - photon absorption caused by coherent superposition of the perturbed levels is experimentally observed

    分析了微擾能級的間隔和疊加程度、激光功率以及中間能級的失諧對量子干涉效應的影響，實驗上觀察了包含有一對微擾疊加中間能級的菱形四能級系統中的雙光子激發現象，發現微擾能級的相干疊加可增強雙光子吸收。
  2. It is well known that electromagnetically induced transparency ( eit ) occurs because of the absorption cancellation by atomic coherence and interference

    我們知道電磁誘導透明（簡稱eit ）是原子相干對光吸收的相消干涉所致。
  3. We study the time evolution law of the atomic response in an open - type inversionless lasing system when the probe or driving field is off - resonance, and compare the law with that obtained when the probe and driving fields are resonant. we find that the detuning has considerable effects on the time evolution law : when the probe or driving fields is off - resonance, the dispersive responses for the probe and driving fields are no longer 0 and the two - photon coherence is no longer a pure real ; the variation of the probe detuning can make the time evolution law of the population distributions and the gain ( absorbtion ) of the driving field changing obviously ; with detuning increasing, the time evolution behavior of the gain ( absorbtion ), dispersion of the probe field and the two - photon coherence will gradually diviate from the evolution law of the standard damped oscillator ; with the driving detuning increasing, the oscillating time of the dispersion of the driving field becomes longer, the amplitude and the stationary value increase

    研究了探測場或驅動場失諧情況下開放的型無粒子數反轉激光系統中原子響應的時間演化規律，並與探測場和驅動場都共振時的演化規律進行了比較.我們發現失諧對時間演化規律有顯著的影響;當驅動場或探測場失諧時，原子對探測場和驅動場色散的響應不再為零，雙光子相干不再是純實量;探測場失諧的變化將使粒子布居和驅動場增益（吸收）的時間演化規律明顯改變;隨著失諧的增大，探測場增益（吸收） 、色散和雙光子相干隨時間的演化行為逐漸偏離標準阻尼振子的演化規律;驅動場色散驅動場失諧量的增加而振蕩時間變長，振幅和穩定值變大
  4. Compared with three - level atomic system, the atomic coherence effects in four - level can lead to eit and eia, which depend on the intensity of control light and the relaxation of the fourth level

    與三能級原子系統相比，四能級原子相干效應即可導致電磁感應透明的產生，也可產生電磁感應吸收現象，取決于控制光的強度和第四個能級衰變率的大小。
  5. Third, the whole absorption spectrum displays, in general, three pairs of absorption peaks and three pairs of gain peaks. due to the coherences between dressed states, these peaks are not exactly at the resonant resonance frequencies between dressed states, but in the vicinity of them

    還有一個特徵就是，吸收光譜在一般情況下會出現三對吸收峰和三對增益峰，在修飾態相干的作用下，這些峰並不是位於修飾態共振躍遷頻率處，而是位於它們鄰域附近。
  6. A coherent electromagnetic pulse in the range between the far - infrared and microwave region is used as a detection source. the amplitude of the wave is recorded by electro - optical or photoconductive sampling. after fast fourier transform, the amplitude and phase of the wave is given, then the complex refractive index standing for the absorption and dispersion of the material in thz region is extracted

    Thz （ 10 ~ （ 12 ） hz ）時域光譜技術是20世紀90年代發展起來的一種新型的光譜測量技術，它使用頻率介於遠紅外和微波之間的相干電磁輻射脈沖作為探測源，利用電光取樣或光電導取樣的方法直接記錄thz輻射電場的振幅時間波形，通過傅立葉變換得到測量信號振幅和相位的光譜分佈，進而獲得材料在thz波段的復介電常數，即色散及吸收等信息。
  7. Recent studies have shown that the quantum coherent population trapping, electromagnetically induced transparency, index enhancement without absorption, etc. these new effects have great potential for the control of the coherence properties of a medium, the production of high frequency lasers, the information storage and high precision measurements

    最近的研究表明，原子相干產生很多新的效應，如相干布居捕獲、無反轉激光、折射率增強、電磁誘導透明、電磁誘導吸收等。這些新效應對光學介質相干性質的控制、高頻激光的產生、光信息存儲和高度測量等方面具有巨大的應用前景。
  8. Quantum coherence and interference have led to the observation of many new effects and new techniques in quantum optics and atomic physics. examples include coherent population trapping, electrom agnetically induced transparency, lasing without inversion, and enhancement of the index of refraction without absorption

    當應用相干場來驅動光學介質時，可以使得介質的吸收和色散關系發生極大改變，產生許多新的效應，如相干布居捕獲、電磁誘導透明、無反轉激光、無吸收折射率增強等。
