分析了国内外有关红外光电探测器激光损伤阈值的大量测量数据。讨论了激光损伤探测器的机理以及目前尚未解决的问题。比较了高重复频率脉冲激光和连续波激光对探测器的损伤效果。分析表明 ,在相同平均功率的条件下 ,高重复频率脉冲激光与连续波激光相比 ,探测器损伤效果前者要比后者大得多 Analysis of a large number of domestic and international infrared photodetector laser damage threshold of a large number of measurements. The mechanism of laser damage detector and its unresolved problems are discussed. The effects of high repetition frequency pulsed laser and continuous wave laser on the detector were compared. The analysis shows that under the condition of the same average power, the effect of the detector damage is much greater than that of the continuous-wave laser with the high repetition frequency pulsed laser
