本文报道了掺钕钇铝石榴石激光器的基波、二次和三次谐波产生的锌和镉等离子体参数的测量。的激发温度已确定从玻尔兹曼绘图方法，而电子数密度估计从斯塔克加宽的几条谱线的配置文件。等离子体的时间演化也进行了研究。此外，我们还计算了Zn（4s5s3S1→4s4p3P0，1，2）和Cd（5s6s3S1→5s5p3P0，1，2）三重态的相对跃迁几率，并与美国国家标准与技术研究所数据库中的数据进行了比较。实验在空气中进行，也在He，Ne和Ar气氛中进行，以研究周围气体环境对原子和离子线的发射强度和对等离子体参数的影响。
We report the measurement of the zinc and cadmium plasma parameters produced by the fundamental, second, and third harmonics of the neodymium-doped yttrium aluminium garnet laser. The excitation temperature has been determined from the Boltzmann plot method, whereas the electron number density is estimated from the Stark broadened profile of several spectral lines. The temporal evolution of the plasma has also been investigated. Besides, we present experimental relative transition probabilities of the Zn (4s5s3S1→4s4p3P0,1,2) and Cd (5s6s3S1→5s5p3P0,1,2) triplets and compare our data with that listed in the National Institute of Standards and Technology database. The experiments have been performed in air but also in He, Ne and Ar atmosphere to study the effects of ambient gas environment on the emission intensity of the atomic and ionic lines and on the plasma parameters.
