摘要:
理论分析拓扑电荷数大小相等、符号相反的两束拉盖尔高斯型涡旋光束的干涉,并从实验上研究拉盖尔高斯型涡旋光束的拓扑电荷数的改变及干涉特性.结果表明,采用加道威棱镜的马赫曾德尔干涉方法,可以容易地分辨涡旋光束的拓扑电荷数,并降低检测的误差.研究还发现,干涉后的光斑图样有缓慢的旋转现象.
Abstract:
Interference of two Laguerre-Gauss vortex beams carrying equal but opposite topological charge is studied theoretically.The change of the topological charge and the interference properties of Laguerre-Gauss vortex beams are explored experimentally.It is found that the topological charges can be easily detected by the Dove-prism method,which greatly reduce the detection error.It’s also fond that the pattern will spin slowly.
