首次解决了含有螺旋相位位错的泵浦光束产生的二次谐波中衍射和坡印廷矢量走离的综合效应。我们预测多个涡旋孪生的自发成核，其随后的爆炸可以产生单电荷涡旋的准排列模式。
The combined effects of diffraction and Poynting vector walk-off in second-harmonic generation with pump beams that contain screw phase dislocations is addressed for what is believed to be the first time. We predict the spontaneous nucleation of multiple vortex twins whose subsequent explosion can yield quasi-aligned patterns of single-charge vortices.
