本文采用３５５ｎｍ脉冲激光脱附和光解一些金属氯化物（ＣｕＣｌ２，ＡｇＣｌ和ＣｓＣｌ）薄膜产生高动能的超热氯原子．用飞行时间质谱法测得生成的Ｃｌ原子的动能分布很宽，最大动能可达６ｅＶ左右．氯化物薄膜厚度对Ｃｌ原子的最大动能有明显的影响．增加激光能量密度将使Ｃｌ原子最大动能迅速增高．此外，还讨论了上述产生起热Ｃｌ原子的机理．
In this paper, 355nm pulsed laser desorption and photolysis of some metal chloride (CuCl2, AgCl and CsCl) film to generate high kinetic energy of ultra-hot chlorine atoms. The kinetic energy of Cl atoms generated by time-of-flight mass spectrometry is very wide and the maximum kinetic energy is about 6eV. The chloride film thickness has a significant effect on the maximum kinetic energy of Cl atoms. Increasing the laser energy density will rapidly increase the maximum kinetic energy of Cl atoms. In addition, the mechanism of generating hot Cl atoms as discussed above is also discussed.
