How electrons in valency and flow as they are connected to the atom and the atom is stationary but the electron travels way more distance than the size of atom that causes conduction?

Imagine we want to create a kugelblitz (a black hole generated by light) by focusing multiple laser beams to the same point in outer space. If I'm not wrong, the beams would simply cross each other at the focus point. Does it mean that, in order to create e.g. a kugelblitz with a 0.1 light-second...
