慣性約束聚變綜合診斷系統It has been shown that : with the increase of the kerr medium intensity parameter u, the rabi oscillation extent of the mean photon number decrease and the rabi oscillation frequency becomes rapid, the antibunching effect becomes strengthened ; with the increase of n, the interaction between the field and atoms gradually becomes weak, however, the interaction between the field and the kerr medium gradually becomes strengthened and happen in advance ; with the increase of the coupling constants of two atoms, the rabi oscillation extent of the mean photon number decrease and the rabi oscillation frequency becomes rapid too, the antibunching effect becomes weak

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。It has been shown that : the little indentation which represents the quantum noise of the system appears in the evolution curves ; the quantum noise which is caused by virtual photon field gradually becomes weak when w increases, the quantum noise increases when n increases ; the virtual photon process make the antibunching effect strengthen, make the squeezing degree deepen obviously, and lead to the additional vibration of entropy, the oscillation extent of the additional vibration of entropy increases when n increases and decreases when co or g increase. besides, the quantum dynamics of two coupling atoms interacting with a single mode ligh t field in a kerr medium is studied in this paper ; the influences of the kerr effect on the mean photon number, the degree of second order coherence of field, the evolution of the field entropy and the squeezing effect are also discussed
)的增大,量子噪聲分別減小和增大;虛光子過程使光場的反聚束效應增強,使光場的壓縮程度明顯加深,並引起了附加的「熵振蕩」 ,這種附加「熵振蕩」的幅度將隨著光場初始平均光子數( ? )的增加而增大,隨著光場頻率和原子間耦合系數g的增大而減小。本文還研究了充滿kerr介質腔中「耦合雙原子-單模光場」相互作用系統的量子動力學性質,研究了克爾效應對場的平均光子數、二階相干度、場熵演化特性及光場壓縮效應的影響。The super resolution effect of sb layer super resolution structure is also investigated with near - field scanning optical microscope. in addition, a rigorous three - dimensional ( 3d ) optical electromagnetic finite - difference time - domain ( fdtd ) model for analysis of a sil system is detailed. in order to accurately analyse sil model, a new method of setting a focused gaussian beam source in fdtd grids is presented
