  1. When a collimated - well gaussian laser beam passes through a 27i - phase plate and then focused by a lens, a focused hollow beam ( fhb ) will be generated behind the lens, as a result of the completely ( r = 0 ) and partially ( r 0 ) destructive interference effects around the central region of the beam

    當一束準直的高斯光束通過具有2位相分佈的位相片和一個薄透鏡時，這將導致在入射高斯光束中心的完全和部分相消干涉效應，於是在透鏡后就會形成一束聚焦中空光束（ fhb ） 。
  2. The results show : ( 1 ) that the dynamical properties in the system depend on the degree of entanglement of the initial two identical two - level entangled atoms and the intensity of the coherent optical field, and the atomic dipole moment can be completely squeezed via choosing optimal degree of entanglement of the initial atoms in the feeblish optical field ; ( 2 ) that the quantum properties of the system also depend on the degree of entanglement of the initial two identical two - level entangled atoms and the intensity of the coherent optical field, and the radiation field can be effectively squeezed via choosing optimal degree of entanglement of the initial atoms in the fee blish optical field

    （ 2 ）相干態光場的強度和兩原子的初始糾纏度對光場的量子特性也有很大的影響。光場的二階相干性質（聚束與反聚束）和光場的壓縮效應均與光場強度和兩原子糾纏度相關聯。在弱光場中，選擇合適的兩原子初始糾纏度，光場壓縮深度和時間可達到最大。
  3. It has been shown that when the partially coherent beams propagate in the atmosphere, it may be less affected by turbulence than are fully coherent ones. moreover in laser fusion a highly coherent beam is transformed into a partially coherent beam, for reducing the speckle and for getting more smooth focused spot

    例如，部分相干光在大氣中傳輸時所受大氣騷動的影響要比完全相干光小得多;並且部分相干光束具有光強比較均勻，對散斑低靈敏等優點而被應用於激光核聚變等領域。
  4. It has been shown that whether resonant or non - resonant interaction system, the kerr effect weakens the coupling of the field - atom, shortens the cycle of quantum collapses and revivals of the atomic level occupation and makes the nonclassical correlation properties steady. kerr effects on the properties of the correlation, on the correlation intensity between the two - mode, on the photon - number distribution and on the bunching or antibunching effect of the two - mode su ( 1, 1 ) coherent states produce obviously different characters when it is changed the initial intensity of the light field. that is to say, kerr effect on the two interaction systems is accorded

    數值計算結果表明：無論是共振還是非共振相互作用， kerr效應均使原子與光場的耦合減弱，原子布居的崩塌與復甦的周期縮短，光場的非經典相關的穩定性增強；在初始光場較弱和較強兩種情況下，類kerr介質對雙模su （ 1 ， 1 ）相干態場兩模間的相關性、相關程度以及光子的聚束與反聚束效應產生的作用均有明顯的區別，即kerr效應對系統在共振及非共振作用時的影響是一致的。
  5. Specifically, they recombine destructively ? that is, the waves cancel each other out

    具體一點講，光束合併時進行相消性干涉，也就是光的波長互相抵消。
  6. In order to improve the existing pr adaptive optical heterodyne detection system ( praohds ), a new praohds is proposed based on sppc and mppc coexistence. the experimental study of the system is completed by equal amplitude ar + laser beams, poorly coherent equal amplitude solid - state laser beams and high speed amplitude - modulated solid - state laser beams through distorting media. experimental results indicate that the new system is applicable

    為了改進現有的光折變自適應光外差探測系統（ praohds ） ，本文利用sppc和mppc同時共存的特性，提出了一種新型的praohds ，並利用ar ~ +等幅激光、相干性較差的固體等幅激光以及固體高速振幅調制激光對新系統進行了畸變光束的自適應光外差探測實驗研究，結果證明了新系統在實際應用中的可行性。
  7. Two spherical waves and multiple spherical waves interference, and yang ' s interference experiments are simulated by using different methods. two spherical waves interference is focused on the on - plane or out - plane of the spot light source plane and the observing plane. then, we analyze how the temporal coherence of optical waves influence the contrast of the interference pattern

    用光波波前疊加的方法實現了對兩列球面波干涉、多光束干涉等實驗的模擬；用傳播矩陣描述衍射光波波前傳播的方法對楊氏雙縫和雙孔干涉實驗進行了模擬，並具體詳細地分析了單縫衍射對雙縫干涉的影響；另外還分析了光場的時間相干性對干涉條紋反襯度的影響。
  8. On the other hand, various techniques using the dhbs have been applied in optical traps for microscopic particles, guiding, cooling and trapping for neutral atoms as well as in manipulations and control of coherent matter waves ( i. e., bose - einstein condensations ( bec ) ) and so on

    同時，其他的一些研究小組開展了暗中空光束在光阱與微粒的操縱、中性原子的激光導引、冷卻與囚禁以及相干物質波（如玻色-愛因斯坦凝聚， bec ）的操縱與控制等領域的應用研究。
  9. At the same time, it uses a frequency translator to obtain a frequency shift, which is equal to the brillouin frequency in fiber. then the detecting pulsed light and the cw reference light can coherent. this method greatly improved the system ’ s sensitive and signal to noise ratio ( snr )

    同時在探測光路中引入一個光移頻環路，使探測光移頻后再經光纖中布里淵頻移，其後向布里淵散射光頻率與參考光束大致相當，可進行相干自外差探測，大大提高了系統的探測靈敏度以及系統的信噪比。
  10. This “ signal beam ” then meets a separate reference beam, and where the two beams intersect they create an interference pattern in a light - sensitive medium

    然後，信號光會和另一獨立的參考光相遇，當兩個光束相交時，它們會在感光介質中製造一個干涉圖樣。
