Out of universe answer: The creators wanted to use a cracked crystal, which gave an unstable force field and thus needed side vents, to emphasize Kylo/Ben's unstable nature.
We've known for years now that Kylo Ren's lightsaber crackles and sputters the way it does because the kyber crystal that powers its blade is unstable.
When Ben Solo became Kylo Ren, he chose a lightsaber with a cracked kyber crystal within it. This meant he had to give his lightsaber an unusual design, using a crossguard hilt with quillons to control and direct the energy streams to each side and prevent the lightsaber overheating.
The lightsaber's redesign was a byproduct of the bleeding process that damaged its kyber crystal, rendering it dangerously flawed and unstable, and necessitating the lateral vents were meant to prevent the cracked kyber crystal from overloading.
It can power the lightsaber because the crystal basically deems it so. I mean kylo's crystal is broken which is why it gives the unstable effect. Its just splitting its power between the two lightsabers that cal was about to create.
Properties. Kathracite crystals were the weakest of the Adegan crystrals and often used to create training lightsabers for the younglings who were apart of the Jedi Order.
The fragments of Cal's crystal weren't broken themselves. They worked as two intact crystals. The information about Kylo's saber first came from here.
Even though Kylo Ren uses a red lightsaber, harnesses the dark side of the Force, and wears a cape, he is not a Sith. Because of that, he can never hold the title of Darth.

It was possible to "heal" the effects of bleeding on a kyber crystal, by using the light side of the Force, thus changing the crystal's color again. The process typically resulted in a white crystal.
The breaks in Ren's mask were meant to be a visual representation of his fractured character. Instead of hiding him as it did before, the mask tells his history, and his behavior is revealed.
When Kylo Ren did this, he poured so much hate and anger into the crystal, causing it to crack. in the lightsaber itself, the crystal was extremely unstable. This is why his lightsaber has that crackling effect. He also made use of cross guards to make sure.
Starkiller Base is a superweapon built into the planet Ilum by the First Order. Like the Death Star I and II, Starkiller Base was capable of destroying entire planets. However, it was superior to the previous models.
A crystal embodies the Jedi as the heart of the lightsaber, and pure kyber has no color until it's bonded to the Force user. This process likely resulted in Rey Skywalker's lightsaber being yellow.

Surprisingly, their findings indicate that the red lightsabres favored by The Sith are physically the weakest of all lightsaber colors. Luke Willcocks determined this by first calculating the strength of Qui-Gon Jinn's green lightsaber.
The weakest and most harmless type of lightsaber is the one that has been “baby-proofed”: the training lightsabers. As the name implies, this type of lightsaber is only utilized in the context of training very young Jedi to one day become Jedi Masters.

Barab ingots were a type of kyber crystal found on the irradiated planet Barab I. The crystals were found in clusters in the planet's mountains and were hot to the touch. They also glowed and, when used in a lightsaber, created a powerful, fiery blade and made the entire lightsaber slightly radioactive.
The Solari crystal was one of the oldest and most powerful lightsaber crystals of the Jedi Order.
The act of Bleeding a lightsaber's Kyber crystal is achieved when a Dark Side Force user channels all of their hatred and suffering into the crystal, imbuing it with Dark Side energy. A Bled Kyber crystal will often appear a little cracked and unstable, and it will give the lightsaber blade a red hue.
