【摘要】 用准分子 XeF 激光（3511）及 N₂激光（3371）泵浦钠蒸汽,得到 Na₂的2.5μm 与9100级联辐射跃迁。分析了2.50～2.56μm 潜区的束缚-束缚跃迁结构及该级联可能的中间态。获得了该谱区的激光振荡及调谐效应。更多还原

【Abstract】 The cascade transition of Na₂ at wavelength of 2.5μ and 9100  has been observed byexciting sodium vapor with excimer XeF laser （3511 ） and N₂ laser （3371 ）.The bound-boundtransition structures of the region in 2.50～2.56μm and possible intermediate state of the cascade tran-sition has been discussed.The laser oscillation and tunable effect has been obtained.更多还原
