以ＹＡＧ调Ｑ脉冲激光为光源，使用ＣＣＤ技术采集样品ＣＵ等离子体瞬态光谱，用玻耳兹曼分布法对激光等离子体的温度进行了测量。当激光脉冲能量为０．１Ｊ时，测量的Ｃｕ谱为原子激发谱，等离子体温度为１４０６３Ｋ。作为对比，用同样方法测量了交流电弧激发的Ｃｕ等离子体温度。所建立的测温方法对于研究激光与物质的相互作用有重要应用前景。
The YAG Q-switched pulsed laser was used as the light source, and the plasma samples were collected by CCD. The temperature of the laser plasma was measured by Boltzmann distribution. When the laser pulse energy is 0.1J, the measured Cu spectrum is the atomic excitation spectrum, and the plasma temperature is 14063K. In contrast, the Cu plasma temperature excited by the AC arc was measured by the same method. The established temperature measurement method for the study of the interaction between laser and matter has important application prospects.
