Antimatter cooled to near absolute zero by laser beam

[Admin]

The scientists trapped the antimatter in a magnetic field to stop it from annihilating, before blasting it with a cooling laser.

This part I find difficult:

" At this point the researchers cooled the antihydrogen cloud by blasting it with a laser."

I would have thought that blasting with energy would increase temperature - but I suppose antimatter has the opposite effect. Is that the easy answer?
