磁约束铜蒸气放电中基态铜原子密度的测量

Measurement of the ground state copper atom density in a magnetically confined discharge

利用吸收方法测量了磁约束铜蒸气放电中的基态铜原子密度，近室温的气体放电条件下得到铜原子密度达１０１４ｃｍ － ３ 量级。结果表明，磁约束放电能够产生激光激励过程所需密度的铜原子蒸气，这为磁约束放电铜蒸气激光器的可行性研究提供了一个重要结论。

Using absorption method,we measured the ground state copper atom density in a magnetically confined discharge,and found that the density of the atom was the degree of 10 14 cm -3 ,and was suited to copper vapor laser action.Comparing with conventional copper vapor lasers,the discharge gas temperature was quite lower.So the results show the feasibility of applying the magnetically confined discharge in copper vapor lasers.
