摘　　要：利用自制装置对激光产生的等离子体发射光谱进行了测试,研究了不同激光能量下的复合谱的一维强度分布,实验结果表明:随着激光能量的提高,等离子体发射强度及最大膨胀距离也相应增加。同时研究了激发态Al原子的特征谱线的飞行谱,并计算出激发态Al原子的飞行速度为2×103m/s。The plasma emission spectrum induced by laser was detected. One-dimension intensity distribution of composite spectra with different laser energy is studied. Experiment results show that the intensity of plasma emission as well as the maximum expand distance of plasma increase with laser energy＇s increasing. Meanwhile the flight spectrum with characteristic spectral line under excitation state is investigated. The flight velocity of Al atoms in excited state is 2×10^3m/s approximately.
