Abstract:

Temperature rise after the absorption of laser and a variety of phenomena caused by temperature rise can cause detectors to suffer varying degrees of injury.The paper makes use of the thermal elastic theory to do research on oxygen-iodine laser's irradiating silicon material.According to a two-dimensional planar model,we can obtain transient distribution of the temperature field and thermal stress field which results from laser irradiation on semiconductor material through function calculation.

Key words: photoelectric detectors;laser radiation effects;temperature field;thermal stress field
