利用流动的空心阴极稀有气体等离子体与氧（O/sub 2/）束交叉，实现了8446.7AA的原子氧激光器。基于能量转移碰撞的激光作用仅在纯氦等离子体中实现。在氦等离子体中加入0.2%氖或0.1%氩后，激光器停止工作，荧光减弱。如果使用其他O供体如CO、CO/sub 2/或N/sub 2/O，则没有观察到荧光。讨论了不同氧施主和稀有气体组合以及不同激发方法的激发机理。>
A flowing hollow cathode rare gas plasma crossed with an oxygen (O/sub 2/) beam was used to operate an atomic oxygen laser at 8446.7 AA. Laser action based on energy transfer collisions was accomplished only with pure helium plasmas. With additions of 0.2% neon or 0.1% argon to the helium plasma, the laser ceased to operate and fluorescence was reduced. No fluorescence was observed if other O donors such as CO, CO/sub 2/, or N/sub 2/O were used. The excitation mechanisms for different O donor and rare gas combinations and different excitation methods are discussed. >
