In Star Wars canon, they're never actually "laser swords", and while there's mention of crystals in them, it doesn't say they're for focussing/controlling light.
The theory I like is that light sabres are a force field encompassing plasma of some sort, which is a much more reasonable explanation as to why they have a finite length and a physical presence.
