| 摘 要： | 利用波长为1064nm、脉宽为10ns的脉冲激光烧蚀Hg0.8Cd0.2Te晶体表面，由光学多道分析仪（OMA）记录其激光等离子体的时间分辨光谱．通过对等离子体线状谱的演化分析得知：等离子体的膨胀过程是一个原子不断被激发的能量交换过程；线状谱的发射机制是碰撞激发．

| Abstract: | The Q-swithched pulsed laser with a wavelength of 1 064 nm and a pulse duration of 10 ns was focused onto the surface of Hg0.8Cd0.2Te crystal,and the time-resolved spectra of the laser-induced plasma were recorded by the optical multichannel analyser(OMA).Through analysis we can conclude that the expanssion of the plasma is a process of energy exchange involving particles being excited continuously.Also the mechanism of line spectrum emission is the excitation of collision. |
