【摘要】 本文报导了钠蒸汽中的受激电子Raman散射（SERS）、受激电子超Raman散射（SEH RS）和黄色锥状辐射等非线性光学效应的研究工作。利用钠蒸汽中的3S—4S SERS和3S—4P_3/2,1/2双支SEHRS过程,获得了2.33—2.65μm的连续可调谐红外输出,对其有关特性进行了分析和讨论。提出了一种共振Raman自发四波参量过程,对黄色锥状辐射的产生机制做了初步解释。更多还原

【Abstract】 A research on nonlinear optical effects in sodium vapor...stimulated electronic Raman scattering （SERS）, stimulated electronic hyper-Raman scattering （SEHRS） and yellow cone radiation is reported in this paper. The infrared output tunable from 2.33 to 2.65μm has been achieved in the 3S—4S SERS process and the 3S—4P_{3/2, 1/2} dual-branch SEHRS process in sodium vapor. Some of its characteristics are also analyzed and discussed in this paper. Finally a Raman-resonent sponteneous four-wave parametric process is presented as an introductory explanation for the yellow cone radiation.更多还原
