摘要

激光诱导击穿光谱技术获得了Al薄片的时间分辨等离子体发射光谱.对同等压强Ar、He、N2和空气环境下采集的离子体光谱进行对比发现

Ar气体环境下得到的Al原子特征谱线强度最强.另外还测得激光诱导产生的Al等离子体初始时刻的温度和电子密度.对比发现

同等压强条件下Ar气体环境产生的Al等离子体温度和电子密度都比其它气体环境中的高.与惰性气体Ar和He相比

双原子分子气体N2对Al等离子体发射线的增益效果不明显.

Abstract

Used laser induced breakdown spectroscopy

obtained the time resolved aluminum plasma emission spectrum. Comparing the plasma spectrum of aluminum obtained under the condition of same pressure of argon

helium

nitrogen and air

respectively

find out that the characteristic spectrum lines of aluminum is strongest in the argon gas environment. Additionally

measured the initial temperature and electron density of laser induced aluminum plasma. By comparision

find out that the aluminum plasma temperature and electron density in the argon gas environment is greater than other gas environment's.Compared with the inert gases of argon and helium

the double atom molecules of nitrogen gas have less enhancement effects for aluminum plasma emission lines.
