Experimental patterns and theoretical analysis of the SP vortices using a PVL with m = −4.

(a) and (b) Experimental patterns using linearly polarized LG_0,−1 and LG_0,−2 modes and a PVL with m = −4. (c) and (d) Experimental data (red lines) of the intensity distribution through the centers of obtained SP vortex patterns corresponding the patterns (a) and (b), respectively and the theoretical fitting (black lines) of experimental data (red lines) with respective functions shown in eq. (2) with n = −5 and −6 and the adjusted size of the pattern.
