基于随机激光时域理论,数值研究了二维随机激光器中横磁模式的输出光谱线宽度,获得了谱线宽度与抽运强度的关系曲线,由此曲线可以计算横磁模式的很多特征参数.从谱线宽度的角度来看,横磁模式的输出特性结果与已有的横电模式结果相比,横磁模式具有较好的输出特性.
Based on the stochastic laser time-domain theory, the width of the output spectral line of the transverse magnetic mode in a two-dimensional random laser was numerically studied. The relationship between the spectral line width and the pumping intensity was obtained. From this curve, many characteristic parameters of the transverse magnetic mode can be calculated. From the spectral line width point of view, the output characteristics of the transverse magnetic mode results compared with the results of the existing horizontal mode, the transverse magnetic mode has better output characteristics.
