摘　　要：本文在考虑了激光在材料内的热源效应后,求解了热扩散方程,给出两种常见情况下激光功率与脉宽、表面温升的关系式,借助探测器表面的温度曲线,给出几种探测器损伤阀值时的表面温度。讨论了探测器破坏的热机理．After considering the laser-induced heat effects in materials, the thermal diffusion equation is solved and the relation of the laser power with the pulse width and surface temperature under two usual conditions is given. The surface temperature of photoelectric detectors under the induced damage threshold is given according to the detector surface temperature curves. The thermal mechanism of detector damage is discussed.
