摘要

利用光学发射光谱技术(OES)对空气中不同能量的Q开关(Nd:YAG)激光照射(Ni)靶后产生的等离子体进行了分析。采用Boltzmann-Plot和Stark展宽方法计算等离子体参数，包括电子密度(ne)、电子温度(Te)、等离子体频率(fp)和Debye长度(λD)。结果表明，(ne)、(Te)、(λD)和(fp)随激光能量的增加而增大，计算得到的电子温度值在0.934 ~ 1.479 eV之间。

Influence of pulse laser energy on the Nickel plasma characteristics that produced in laser-induced plasma system

Optical Emission Spectrometry technique (OES) is used to analyze the plasma generated from a (Ni) target illuminated with a Q- Switched (Nd:YAG) laser at various energies in the air. Boltzmann-Plot and Stark broadening methods were used to calculate the plasma parameters including electron density (ne), electron temperature (Te), plasma frequency (fp), and Debye length (λD). It is shown that the values of (ne), (Te), (λD) and (fp) increase with increasing laser energy with the calculated electron temperature values ranging between 0.934 - 1.479 eV.
