Let me explain. A lightsaber works by generating a powerful electrical charge, which the crystal focuses into plasma, which the magnetic containment field then shapes. Depending on the crystal, the plasma blade might have an added connection to the Force. That part we can't understand, obviously. When your lightsaber has 2 crystals, the blade is focused and strengthened further, allowing it to be water-resistent. If it has 3 crystals, the blade might even be able to fight cortosis, depending on the type of crystal. The reason why Kylo Ren's lightsaber has the lateral side-vents is because he has a cracked crystal, which can barely contain the charge. I hope that helps.
