According to a new article in Phys.org https://phys.org/news/2019-02-repulsive-photons.html
Scientist have found a way to make photons repel each other
Long story short they convert the photons which normally do not interact into polaritons: https://www.nature.com/subjects/polaritons "Polaritons are hybrid particles made up of a photon strongly coupled to an electric dipole" and this allows the photons to repel since they have charge.

You can't cut someone's arm off with that. At least, not with the ease seen in the movies.

I don't know about in the movie, but I believe in the book of The Last Jedi that's basically what the executioners' axes are.
