Contrastive experimental research of soft-damage on CCD irradiated by XeF laser and YAG frequency-doubled laser

In order to study the effects on visible CCD array irradiated by XeF(C-A) laser and YAG frequency-doubled laser,the experimental platform for pulse laser radiating CCD and CCD synchronous image-acquiring system were set up.Based on the experimental platform and the acquiring system,the radiating effect experiments on CCD by the both lasers were carried out,laser energy thresholds and CCD images under soft damage (including local saturation,full saturation,saturation crosstalk,full-screen saturation) were acquired.The data and CCD images were processed and analyzed by means of laser energy density threshold method and saturated area method respectively.The results show that XeF(C-A) blue-green laser and YAG frequencydoubled laser have the same radiating effects on SONY SUPER HAD visible CCD array.
