由混合激发钠分子-原子系统产生的强度振荡变化的红外受激喇曼散射
The generation of intenity-oscislated IR stim ulated Raman scattering based on hybrid excitation of Na2-Na system
【摘要】 本文报道以等频二步激发钠分子-原子系统,观测到强度随泵浦光的调谐而呈振荡变化的3P—4P受激喇曼散射,以及对应4D—4P和4F—3D跃迁的红外受激辐射和由四波混频产生的816.8～822.1nm区内可调谐相干辐射。文中对这些过程进行了分析讨论。
【Abstract】 The intensity-oscillated IR stimulated Raman scattering was observed in Na2-Na system by using two-step equal-frequency excitat on. The intensity of which oscillates with pump wave length. Besides, the IR stimulated radiation of 2.338μm (4D-4P) a nd 1.84μm (4F-3D) and tunable coherent radiation in the region of 816.8～822.1 nm were generated. The results were analysed and discussed in detail.
