In this paper, a series of effects of CCD interaction with laser are taken together in consideration. These effects dividethe light intensity axis into three sections named respectively as 'normal', 'dazzle' and 'damage', along the positivedirection. For the effects on first two sections, a general model is proposed to describe them, which reflect theperformance jump charateristics of CCD under laser irradiation. In fact, the model contains the jump functions of threeperformance parameters, which are response efficiency, charge transfer inefficiency and leakage current. Thereinto, thefirst is used to describe the pixel itself, and the remaining two are used to describe the influence between pixels. Theleakage current parameters include a variety of situations, such as the leakage current between pixels, the leakage currentbetween channels and even the leakage current between subarrays in a large array. When all three kinds of parametersdon't jump, the CCD works normal. When anyone of them jumps, the CCD is dazzled by light. Of course, the parameterjump in a dazzled CCD can return to normal when light intensity decreases. However, the damage section on lightintensity axis is temporarily not described in this paper. After all, the damaged CCD is not a CCD again.
