From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
The Daichiretsuzan (大地列斬, Daichiretsuzan; Literally meaning "Great Ground Split Slash") is a powerful and long, blade-like energy beam used by Freeza in his Final Form. Final Form Freeza puts his middle and index fingers together and charges an energy sphere on the tips. He then swings the energy sphere around, creating a large Death Beam in the form of a giant, razor-sharp energy blade that can slice through anything.
Dragon Ball Z
Freeza used this attack in his battle against Son Goku on Planet Namek. Freeza was beating Goku around and Goku soon landed on a cliff. Freeza then charged and fired the Daichiretsuzan at Goku and it appeared that Goku was killed. When Goku opened his eyes, however, it was revealed that Freeza had aimed the attack away to carve a fissure going across the entire circumference of the planet.
It is named Death Wave in the Budokai video game series and is one of Freeza's attacks in his Final Form.
