Aiming at the damage mechanism of visible light imaging detector irradiated by high power tactical laser,the damage simulation and experimental study on CCD detector by high power continuous laser at 1080 nm band are carried out.Firstly,based on the typical structure of CCD and the material characteristics of each layer,the thermal damage model of CCD detector caused by continuous laser is established.The transient temperature field and stress field of each layer of CCD are simulated,and the time evolution law of continuous laser damage to CCD multilayer structure is analyzed.Secondly,the damage experiment of CCD detector by continuous laser is carried out to obtain the CCD damage threshold,and the melting of each layer of the CCD detector is analyzed by metallographic microscope and scanning electron microscope.Finally,the results of model simulation and damage experiment are compared,and the reasons for the difference in damage thresholds are analyzed.The results show that the simulated damage threshold of visible CCD detector irradiated by 1080 nm continuous laser for 400 ms is 1.45×106 W/cm2,and the experimental damage threshold is 2.13×106 W/cm2,with an error of about 31.9%.The simulation and experimental results have certain reference significance for exploring the damage mechanism of CCD detectors irradiated by high power laser and evaluating the interference effect.
