以热辐射谱的温度反演为例,介绍了光谱技术在强激光毁伤过程中的应用。利用自制的高速光谱测量系统,实时采集了毁伤过程中的辐射光谱,基于普朗克黑体辐射原理,反演了毁伤区的温度,并应用主成分回归算法,计算得到了毁伤区的温度分布,实现了强激光辐照靶材过程中瞬态温度和温度分布的测量。光谱测量区在200～1 000 nm时,所对应的温度反演为700～6 000℃。

The applications of spectral technologies in intense laser damage are introduced by taking the temperature retrievals of thermal radiation spectra for example.A self-made high speed spectrum measurement system is used to collect radiation spectra for intense laser damage in real-time.The damage zone temperature is obtained through the temperature retrieval based on the principle of Planck′s black body radiation,and the temperature distribution of a damage zone is calculated by using the principal component regression.The measurements of transient temperature and temperature distribution for intense laser irradiating targets are realized,and the spectral range is 200-1 000 nm corresponding to the temperature retrieval range for 700-6 000 ℃.
