[Star Wars] Does the lightsaber of a more powerful jedi/sith have more "cutting" power?


We're shown that it Qui-Gon isn't able to instantly melt through a thick metal door with his lightsaber. He has to slow down a bit.

Would a more powerful jedi/sith - Yoda or Sidious, for example - be able to slice through with a quick slash?

A lightsabers power is determined by two things; the Kyber crystal within and (in Legends) they can be tuned to different settings, ranging from combat to training modes.

The wielder of the weapon only contributes to its power in terms of their skill at fighting with it, they didn't contribute in any way to the actual output of the blade.

I can't remember if it's still canon or in legends but typically a Sith's lightsaber was more fragile due to the damage dealt to the kyber crystal.
