A semi-infinite thermal model is presented which describes temperature rise in photoelectric detector under pulsed laser irradiation. The laser disturbance and damage thresholds with the detectors temperature rise are analyzed. The results show the disturbance and damage of detector are independent of the CO2 laser pulse-width, only depend directly on the energy density, at the same time, the disturbance threshold is one order lower than damage threshold. A numeric analysis about pulse CO2 laser irradiating satellite-borne HgCdTe detector is given. The feasibility of high average repetitive pulse laser disturbance and damage satellite-borne detector is qualitatively analyzed.
