Equally objectionable is the fact that saturation by spontaneous emission reduces the gain exercised by an incoming signal.
同样不利的事实是，自发辐射引起的饱和减少了入射信号所能获得的增益。We also investigate the spontaneous emission properties of a two-level atom embedded in a three-dimensional anisotropic photonic crystal.
本文还研究了处于各向异性的三维光子晶体中，且在强相干的低频场的驱动下的单个二能级原子的自发辐射性质。The results showed that the spontaneous emission rate depends on the width and refractive index of the two-layer dielectric.
结果表明自发辐射率和两层电介质的宽度和折射率有关。We studied the spontaneous emission from a three level atom with an external driving field in a photonic crystal.
文章讨论了在驱动场作用下，三能级原子在光子晶体中的自发辐射问题。This study provides a new understanding on the spontaneous emission rate of an atom in different dielectric slab.
本文的结果为原子在不同电介质间的自发辐射率的研究提供了新的理解。By applying this scheme, in presence of spontaneous emission, the decoherence can be efficiently suppressed.
通过应用这种机制，在存在自发辐射的情况下，可以有效地抑制退相干。Dark lines and a narrow spontaneous line may be produced in isotropic PBG.
各向同性PBG中，自发辐射谱出现了暗线和窄的自发辐射线。Moreover we add the cavity decay and the spontaneous emission of the atom to the system.
我们在系统中加入了腔衰减和原子自发辐射。This text analyzed the ASE-noise induced timing jitter which affected the pulse propagation in dispersion-managed WDM systems.
本文对色散管理孤子系统中存在的影响脉冲传输的ASE（放大器自发辐射）致定时抖动进行了研究。
