核泵浦气体激光研究

Study of Nuclear Pumping Gas Laser

本文介绍了利用核能激励Ｎｅ、Ｈｅ、Ｘｅ、Ａｒ等气体产生激射这一领域内所取得的成果．利用￣（２３８）Ｐｕ源激励Ｎｅ、Ｈｅ－Ａｒ、Ｎｅ－Ｈｅ、Ｎｅ－Ｈ＿２体系，测到了Ｈｅ、Ｎｅ、Ａｒ、Ｈ＿２对Ｎｅ（２ｐ＿１）态的倒空速率常数．利用３００￣＃稳态堆激励Ｈｅ－Ｈｅ体系，测得其增益为２×１０￣（－２）／ｃｍ．在ＣＦＢＲ－Ⅱ脉冲堆上进行了Ｈｅ－Ａｒ－Ｘｅ体系的激射实验，测到了激光信号，其波长为１．７３μｍ，激光功率约为１０ｍＷ．

The results of nuclear pumping Ne, He, Ar, Xe are introduced in this paper.￣(238)Pu was used to exite Ne, Ne-Ar, Ne-He, Ne-H_2 systems. The elimination rate constantsof Ne (2p_1 ) by Ne,He,H_2,Ar were measured. 300￣# stable reactor was used to encourage HeNe system, the gain measured was 2 ×10￣(-2)/cm. Lasing experiment of He-Ar-Xe system wasdone on CFBR-Ⅱ pulse reactor, lasing sign was measured, λ=1.73μp, lasing power wasabout 10 mW.
