University of Washington researchers used an infrared laser to cool a solid semiconductor material — labeled here as “cantilever” — by at least 20 degrees C, or 36 F, below room temperature. Credit: Anupum Pant To the general public, lasers heat objects. And generally, that would be correct. But lasers also show promise to do quite the opposite — to cool materials. Lasers that can cool materials could revolutionize fields ranging from bio-imaging to quantum communication. In 2015, University of Washington researchers announced that they can use a laser to cool water and other liquids below room temperature. Now […]
