This study offers an interesting look at Bessel beam propagation in gyroanisotropic crystals with optical activity, but a couple of things could use more clarification. First, while the paper discusses optical vortex formation in birefringent media, was there any experimental validation? Using interferometry or polarization-resolved imaging could help confirm the predicted beam transformations. Also, since the study is based on theoretical formulations, were any numerical simulations run to check how well the predictions hold up?
The study explores Bessel beam propagation in gyroanisotropic crystals, but how do the authors account for potential experimental deviations from the theoretical model? Were any corrections or calibrations applied to compensate for imperfections in beam generation or crystal alignment that could impact the observed optical vortex structures?
