激光辐照Si-CCD热力效应的研究

由于光电探测器吸收激光后的温升、以及由于温升造成的各种现象,均能使探测器遭受到不同程度的损伤.丈中利用热弹性理论对氧碘激光器辐照硅材料进行研究,建立二维平面模型,通过解析计算得到由激光辐照半导体材料引起的温度场和应力场的瞬态分布.

Study of Thermal and Mechanical Damage in Si-CCD Induced by Laser

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.
