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.
Remember how in TESB, Han and Leia land in an asteroid crater/cave to hide and go out in the vacuum with nothing but an emergency airplane O2 mask thinking that’s OK? And gravity is earth normal gravity?
I’m pretty sure “a galaxy far far away” means the laws of physics are a bit different.
Also, let people enjoy things.
While that happening, there are also TIE bombers flying past dropping bombs on them.
