【摘要】 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。更多还原

【Abstract】 Employing Q-modulating YAG pulse laser as source, using metal Cu as sample, usingCCD detector to collect the transient spectrum and using Boltzmann distribution method, the temperature ofthe laser plasma is measured. From the results we know when the laser pulse energy is 100mJ, Cu spectrummainly consists of atomic excitation lines and its temperature is 14063.8K. This work has great potential forinvestigating the interaction processes between laser and matter.更多还原
