An In-Depth Guide To How Lightsabers Actually Work

While they might be the most recognizable part of Star Wars, the technology behind lightsabers has never really been explained on screen. So, how do lightsabers work? Audiences may have picked up on the fact that kyber crystals were mentioned as the source of power for lightsabers in Rogue One, but only if they were paying close attention. It's certainly true that kyber crystals (otherwise known as lightsaber crystals or focusing crystals) are the most important part of building a lightsaber, but there's far more going on inside the hilt of one of these Star Wars weapons.

Lightsabers are intricate tapestries of electronics and Force power that take great skill to both build and use. Lightsaber designs are as varied as their wielders, but they all have similar components at their center. Jedi, Sith, and really every Force-user employs minor differences in the way they construct their weapons, but there's a standard process behind their creation and use. If you've ever been curious how a lightsaber works, you don't need to rely on the vauge riddles of tiny orange aliens with huge glasses. Here are the cold, hard, lightsaber-y facts.
