Field characteristics of two OAM modes under the first and second setup. (a, e) and (b, f) refer to the field characteristics when producing OAM modes 1 and 2 in the aligned system, while (c, g) and (d, h) are the field characteristics when producing OAM modes 1 and 2 in the misaligned system. (a, b, c, d) refer to the phase profiles and (e, f, g, h) correspond to the intensity patterns.
