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 mean… they do take pause when a Mandalorian is shooting. They may block lasers but putting a lightsaber in front of a slug 6 inches from your face just turns you into Swiss cheese.
Also, their flamethrowers. A lot of mandalorian weapons were utilized solely to counter force users.
