How do I calc vaporizing a hole through earth?

[Arceus0x]

A laser shoots through the earth, going from one side to another. It vaporizes everything in its path and end sup in space.
How do I calc it?
My issue isn't the general idea (get the width of the laser and then calc a cylinder) but rather the fact that most of the destroyed material will be heated magma. It is way easier to vaporize heated magma than normal cold rock. What do?

It varies a lot, we don’t really account for the immense pressure all of that stuff is subject to when calculating it, and the higher pressure is the higher the boiling point becomes, so you need significantly more heat to vaporize magma in the mantle than you would need for lava on the surface.
