Study of damage effect in CCD detectors irradiated locally by laser

When a CCD detector is locally irradiated with a laser,the working features of the CCD detector will vary in laser energy density. Extremely,the CCD detector will be damaged. The saturation thresholds of CCD detector,irradiatedwith a CW 1060 nm or 632.8 nm laser, have been measured respectively,The mechanism of saturation and damage of CCD detector have been discussed in this paper. By employing one dimension non-conducting boundary condition,the thermal saturation threshold hasbeen calculated.
