Where does the rust go? Does it evaporate? Or does the laser turn it back into unrusted iron? Someone explain this to a guy who was bad at science in school

A quick google search told me it is turned into a gas through either vaporization or sublimation so yeah it essentially evaporates the solid debris materials.

I just thought the heat was enough to break the iron oxide back into iron and oxygen, like regular smithing would do.

Vaporized iron dust is probably not a good thing to breathe in.

It can. But that would not stick it back on the solid surface. At least not a meaningful amount.
