| Abstract: | 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. |

| Keywords: | photoelectric detectors laser laser induced damage threshold temperature |
