摘要
由相对论电子束激发稀有气体和碱金属Rb的混合蒸气,观察到来自准分子的橙红色发射带。实验研究了橙红带随温度和抽运功率的依赖特性。当抽运强度超过10 mJ/cm3时,观测到自发辐射放大(ASE)现象和一个最大值为3.5%cm-1的有效增益系数(603 nm处)。
Abstract
An amplified spontaneous emission and a maximum net gain coefficient of 3.5% cm-1 of the Rb2 orange band (601~608 nm) were observed from the e-beam-excited mixture of Rb/Rb2 vapor with argon buffer gas. The dissociative recombination of Rb+3 was discussed as an efficient form ation process of the upper state by the electron beam pumping.
