对多脉冲激光损伤CCD探测器进行了实验与仿真研究。采用波长1 064 nm，脉宽100 μs的激光器，在频率1、3和5 Hz工作条件下，对CCD探测器进行激光损伤实验，观察到多脉冲损伤CCD的三个阶段，得出了CCD探测器的损伤阈值。建立了多脉冲激光损伤CCD探测器的仿真模型，利用有限元法对CCD的损伤阈值进行仿真计算。研究表明，在相同频率的激光辐照下，随着激光脉冲数的增加，CCD的损伤阈值逐渐减小。在脉冲数一定的情况下，重复频率较低，重复频率对CCD损伤阈值影响不大。仿真结果和实验结果吻合良好。

Experiments and simulations of multi-pulse laser damage CCD detectors were carried out. Using a laser with a wavelength of 1 064 nm and a pulse width of 100 μs, the laser damage experiment was performed on the CCD detector under the operating conditions of 1, 3 and 5 Hz. The three stages of multi-pulse damage CCD were observed and the CCD detection were obtained. The simulation model of multi-pulse laser damage CCD detector was established. The finite element method was used to simulate the damage threshold of CCD. The research shows that under the same frequency of laser irradiation, the damage threshold of CCD decreases with the increase of the number of laser pulses. When the number of pulses is constant, the repetition frequency is low, and the repetition frequency has little effect on the CCD damage threshold. The simulation results agree well with the experimental results.
