摘　　要：在稳态核反应堆上,测定了热中子辐照下,~3He-Ne激光体系(P_(He:P_(Ne)=5:1,P_总=4×10~4Pa)的增益系数(丸=632.8nm,跃迁3S_2-2P_4)。当热中子通量为2×10^(12)n/cm^2·时,其增益系数为1.7×10^(-2)/cm。研究了增益系数随热中子通量的变化关系,讨论了温度对增益的影响。实验表明核泵浦~3He-Ne体系有可能实现激射。Laser gain(= 632.8nm, transition 3S2-2P4)of 3He-Ne laser system (PHe: PNe = 5:1, Ptetal = 4x 104Pa) radiated by thermal neutron from steady operation reactor is measured. The measured gain coefficient is 1.7x10-2/em at thermal nuetron flux of 2 x 1012n/cm2-s-Gain curve vs flux of thermal neutron is investigated. The influence of temperature on gain is discussed. The test shows the possibility of lasing from nuclear-pumped 3He- Ne laser system.
