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 ℃.
