| 摘 要： | 提出了热及电场诱导的多载流子模型。在完全耗迟近似下，得出了耗尽区厚度和电场强度的计算公式。公式表明，耗尽区厚度、耗尽区最大电场与诱导时外界电压成平方根关系，而二次谐波的转换效率与应用电压成平方关系。耗尽区的厚度为3-8um；耗尽区的最大场强为1－4V/nm，并位于阳极表面下1－6um.

| Abstract: | The multiple-carrier model for thermal/electrical poling is presented.Under the approximation of the full depletion,the calculating formulas for the width and electrical field of depletion region are obtained.They show that the relationship for the width and the maximum electrical field in depletion region against the applied voltage is square-root,while the conversion efficiency of second-harmonic generation is square with voltage.The width of the depletion region is 3～8 μm,and the maximum electrical field below the anode surface 1～6 μm is 1～4 V/nm. |
