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.
star trek, and some other scifi genre captures it better, SW is more for children, it also magic-tech in it, so not really a true scifi.
It’s a Sci-fi space opera.
Literally. No point in it being hyper realistic
SW is for children is not a great take. It’s just not sci-fi, and shouldn’t be judged as such. It’s a space fantasy, and it leans into the camp and the suspension of disbelief. They use wings and aerodynamics in space. Destroyed ships “sink.” The good guys never get hit and the bad guys die in one shot. Now, the new movies were absolutely disappointing, but Star Wars was never sci-fi, at least not in the ways this discussion is defining the genre.
