Probably a stupid question, but will we ever have something like a microwave to make things cold? Is there a reason this can't exist?

There's a lot of posts here not answering the question or saying it's impossible.
A reverse microwave is possible.
The 1997 Nobel Prize in physics was awarded for the development of methods to cool and trap atoms with laser light.
It's just very hard to do and no one has successfully cooled a large complex object with laser-based cooling.
TIL, that's cool.
