Multitwist optical Möbius strips

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.
