【摘要】 本文报导了碲分子激光新介质的研究工作。采用r—中心矩法从理论上计算Te₂的电子跃迁矩和F—C因子,进而得到其它激光参数,并从实验上论证其可靠性。在476.5nm染料激光激励下,580℃和5正饱和蒸汽Te₂的BO⁺_v（v′=3）-XOg⁺（v″）跃迁参数为:电子跃迁矩2.2±0.3D,峰值F—C因子0.03～0.07,受激发截面10^-14cm²量级,峰值小信号增益系数0.2～0.3cm^-1。更多还原

【Abstract】 This Paper reports the research work on a new laser medrum Te₂. A fluorescence progression for the BO_U⁺（v′=3）—XO_?⁺（v^″） transitions of Te₂ were obtained theoretically by the method r-centroids and experimentally by selective excitation at 4765 with a tunable dye laser, respectively.A comparison of both results shows an agreement.The electronic transition moment 2.2+0.3D, Franck-Condon factor of 0.03-0.07 and the stimulated emission cross section of ～10^-14cm² for tellurium dimer are first reported here.更多还原
