【摘要】 受激辐射机制的研究是光子晶体激光器设计中的一个基本问题。采用全量子理论 分析光子晶体中单个二能级原子的受激辐射。讨论的原子能级间跃迁频率在光子带隙内且接 近带隙边缘。在光子晶体中初态光场影响着系统的行为，激发态粒子数布居出现了有趣的现 象：反束缚、周期振荡和准周期振荡。受激辐射的性质明显与初始态的光场和原子激发态能级 相对光子带隙的位置有关。更多还原

【Abstract】 The stimulated emission from a two-level atom embedded in a photonic band-gap structure is studied. The initial electron- magnetic field in the photonic crystal affects the dynamics of the system , and leads to some novel behavior of the population in the excited state anti-trapping , periodic oscillation and quasi-periodic oscillation. It is shown that the properties of the stimulated emission from an atom in a photonic band-gap crystal strongly depend on the initial field and the relative position of the upper level from the forbidden gap.更多还原
