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.

Looks like my light saber really can be made. Now I just need to find a source for Kyber Crystals https://www.starwars.com/databank/lightsaber-crystal

    Why does the light saber need to be free of any solid matter in the center of the light? I think a very bright LED in a nearly indestructible telescoping tube could match what was seen in the movies just as well. Did I miss a scene?

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

      Just make the LED really sharp: https://en.wikipedia.org/wiki/Monomolecular_wire [wikipedia.org]

        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.

    What about the scene where Qui-Gon shoves his light saber into a sealed bulkhead to melt it? That means it definitely wasn't solid or at least it automatically retracted.
