Star Wars universe does have lasers of all scales and power levels.
Yet literally no one uses them well on a personal scale.
The Jedi (and Sith for that matter) imbue it with a power of magical stone, and then…use it as a saber.
To balance this stupidity, stormtroopers, clones and droids all use slow, non-continuous energy blasters. With actual lasers, they could insta-kill any Jedi, but they cannot, because otherwise the movie wouldn’t exist.
I’m sure there are other references, too, but for it to be a power current it needs to flow to and from a terminus. See also the Tagge Protoblade in which the energy circles around a metal core (internally referred to as the corn dog lightsaber) instead of being a sword
I get that, sort of, that… some kind of supernatural/extradimensional energy is essentially drawn into, and then focused by the kyber crystals and the modulation systems of a light saber…
I just had not heard that they involved a mechanically spinning component.
