Circularly polarized Gauss-Laguerre GL00 and GL01 laser beams that cross at their waists at a small angle are shown to generate a quasi-paraxial field that contains a line of circular polarization, a C line, surrounded by polarization ellipses whose major and minor axes generate multitwist Möbius strips with twist numbers that increase with the distance from the C point.
环形偏振高斯-拉盖尔 GL00 和 GL01 激光束以小角度在腰部交叉,被证明会产生一个准傍轴场,其中包含一条圆偏振线,即 C 线,周围是偏振椭圆,其长轴和短轴产生具有增加的扭数的多重扭曲的莫比乌斯带,这些扭数随着与 C 点的距离的增加而增加。
