摘要
本文用光学多道分析仪测量了用Ｎｄ：ＹＡＧ激光烧蚀固体等离子体的发射光谱，得到了延时Ｔｄ＝１至１０μｓ时Ｍｇ的５５２．８４，５１６．７４，４７０．３０，３８３．８３ｎｍ等谱线的Ｓｔａｒｋ展宽，采用半经典理论和电偶极近似，对Ｔｄ＝１μｓ和２μｓ时上述的谱线的Ｓｔａｒｋ展宽从理论上进行了计算，理论结果与实验符合得很好。
The emission spectra from the plasma produced by using Nd: YAG laser to ablatethe solid Mg sample was measured with an optical multichannel analyzer. The Starkbroadening of Mg 552. 84, 516. 74, 470. 30 and 383. 83 um lines were obtained for adelaying of 1 to 2 us time. The Shark broadening of above lines for Td = 1 us and 2 us weretheoretically calculated with the semiclassical method and electric dipole approximation. Thecalculatedl results consisted with the experimental ones very well.
